-        [LFC] Add support for min/max-height percentage values.
-        https://bugs.webkit.org/show_bug.cgi?id=189391
-
-        Reviewed by Antti Koivisto.
-
-        The percentage is calculated with respect to the height of the generated box's containing block.
-        If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element
-        is not absolutely positioned, the percentage value is treated as '0' (for 'min-height') or 'none' (for 'max-height').

-        The parsing work was already done, this just hooks up the data we have
-        with the CG functionality for conic gradients. Add the needed plumbing

-        [macOS] Cannot change font size at selection until font panel is shown
-        https://bugs.webkit.org/show_bug.cgi?id=189295
-        <rdar://problem/35593389>
-
-        Reviewed by Ryosuke Niwa.
-
-        Currently, attempting to alter the font size of currently selected editable text in WKWebView via menu items
-        will fail if the font panel has never been shown. This is because WebViewImpl::changeFontFromFontPanel, which is
-        responsible for converting the current font at the selection to the new font using -[NSFontManager convertFont:]
-        bails as a result of NSFontManager's currently selected font always being nil.
-
-        WKWebView is responsible for keeping NSFontManager up-to-date with the currently selected font; in fact, this
-        was initially the case in r180465, which introduced NSFontManager support in WebKit2 by propagating EditorState
-        updates that contained font information for the current selection. However, this regressed performance due to
-        selected font computation triggering extra layout passes; r180768 addressed this by introducing a mechanism for
-        requesting the font at the current selection, and only updating NSFontManager with the new selected font when
-        the shared font panel is visible (determined by KVO on NSFontPanel). However, this again regressed WKWebView
-        launch performance, due to KVO registration always forcing the shared NSFontPanel to be created. r182037
-        addressed this by only registering for KVO on the font panel if the WKWebView has been made editable (SPI on
-        WKWebView).
-
-        This leads to two issues when attempting to alter font attributes using macOS UI: (1) in web views that have not
-        been made editable using SPI, showing the font panel and attempting to change the font fails due to the selected
-        font staying nil, because we've never begun registering for KVO notifications on the font panel so we don't try
-        to keep the font manager up to date. (2) Even if the web view is made editable, if the font panel is never
-        shown, then the font manager still won't be kept up to date with the current selection, so changing fonts using
-        menu items still does not work.
-
-        We fix both of these problems by refactoring font manager support on WebKit2 such that an up-to-date selected
-        font in the UI process is no longer necessary in order to alter the font at the current selection. To do this,
-        we figure out what changes the NSFontManager would've made to the currently selected font in the UI process, and
-        then propagate this information to the web process, where we convert this information into an EditingStyle which
-        we apply to the current selection.
-
-        The code to both determine the attributes changed by NSFontManager and to convert these attributes into editing
-        styles to be applied via Editor already exists in WebKitLegacy, in WebHTMLView.mm. This patch moves this
-        existing logic into WebCore and teases it apart into two portions: the first portion probes NSFontManager to
-        determine which aspects of the font changed and constructs FontChanges, which captures these differences. The
-        second portion maps FontChanges to an EditingStyle, which can then be applied to the current selection. In
-        WebKitLegacy, we construct FontChanges using the font manager, and then immediately use it to create and apply
-        an EditingStyle. In WebKit, we construct FontChanges in the UI process using the font manager, and then send
-        this over to the web process via WebPage::changeFont, which then creates and applies the EditingStyle.
-
-        Note that this patch also introduces FontAttributeChanges, which is similar in concept to FontChanges, but
-        captures a broader range of changes possible via NSFontPanel. This was done so that we can eliminate all of the
-        font manager probing code (along with the two specimen fonts) from WebHTMLView, but is also necessary in order
-        to allow changing font shadow, strikethrough, and underlines via the font panel to work in WebKit2. This will be
-        fixed in a followup, by making FontAttributeChanges IPC encodable and by making WKWebView/WKView respond to the
-        -changeAttributes: selector.
-
-        Changes in behavior to WebKit2 are covered by new API tests; legacy WebKit behavior should remain unchanged.

-        IntersectionObserver leaks documents
-        https://bugs.webkit.org/show_bug.cgi?id=189128
-
-        Reviewed by Simon Fraser.
-
-        Currently, Documents own IntersectionObservers while IntersectionObservers own callbacks
-        that have strong references to Documents. To break this cycle, make Documents only have
-        weak pointers to IntersectionObservers. Instead, manage the lifetime of an
-        IntersectionObserver as an ActiveDOMObject, overriding hasPendingActivity to keep
-        the observer alive while there are ongoing observations.
-
-        However, there is a still a potential reference cycle. The callback keeps global
-        references alive, so if there's a global reference to the observer in JavaScript,
-        we have an observer->callback->observer cycle, keeping the callback (and hence the Document)
-        alive. To break this cycle, make IntersectionObserver release the callback when its
-        Document is stopped.
-
-        With these changes, there are no longer any leaks reported with run-webkit-tests --world-leaks

-        Add basic support for ScrollIntoViewOptions
-        https://bugs.webkit.org/show_bug.cgi?id=189258
-
-        Reviewed by Simon Fraser.
-
-        This patch introduces a new ScrollIntoViewOptions parameter that can be passed into
-        Element.scrollIntoView instead of a boolean. A basic support for scroll alignments is
-        implemented, so that it is closer to the behavior of the CSSOMView spec while still remaining
-        compatible with the current boolean-parameter implementation. Full implementation that
-        takes into account orientation/direction will be handled in bug 161611. This patch is also a
-        preliminary step to support the ScrollBehavior (bug 188043) for ScrollIntoView.

-        slotchange event doesn't get fired when inserting, removing, or renaming slot elements
-        https://bugs.webkit.org/show_bug.cgi?id=189144
-        <rdar://problem/43871061>
-
-        Reviewed by Antti Koivisto.
-
-        This patch implements `slotchange` event when a slot element is inserted, removed, or renamed in the DOM tree.
-        Let us consider each scenario separately.
-
-        Insertion (https://dom.spec.whatwg.org/#concept-node-insert): In this case, we must fire `slotchange` event on
-        slot elements whose assigned nodes have changed in the tree order. When there is at most one slot element for
-        each name, this can be done by simply checking whether each slot has assigned nodes or not. When there are more
-        than one slot element, however, the newly inserted slot element may now become the first slot of a given name,
-        and gain assined nodes while the previously first element loses its assigned nodes. To see if the newly inserted
-        slot element is the first of its kind, we must travere the DOM tree to check the order of that and the previously
-        first slot element. To do this, we resolve the slot elements before start inserting nodes in
-        executeNodeInsertionWithScriptAssertion via SlotAssignment::resolveSlotsBeforeNodeInsertionOrRemoval. Note that
-        when the DOM tree has at most one slot element of its kind, resolveSlotsBeforeNodeInsertionOrRemoval is a no-op
-        and addSlotElementByName continues to operate in O(1). Becasue addSlotElementByName is called on each inserted
-        slot element in the tree order, we do the tree traversal upon finding the first slot element which has more than
-        one of its kind in the current tree. In this case, we resolve all other slot elements and enqueues slotchange
-        event as needed to avoid doing the tree traversal more than once.
-
-        Removal (https://dom.spec.whatwg.org/#concept-node-remove): In removal, we're concerned with removing the first
-        slot element of its kind. We must fire slotchange event on the remaining slot elements which became the first of
-        its kind after the removal as well as the ones which got removed from the tree if they had assigned nodes.
-        Furthermore, the DOM specification mandates that we first fire slotchange events in the tree from which a node
-        was removed and then in the removed subtree. Because we must only fire slotchange event on the first slot element
-        of its kind which has been removed, we must resolve the first slot elements of each kind before a node removal
-        in removeAllChildrenWithScriptAssertion and removeNodeWithScriptAssertion as we've done for insertion. Again,
-        in the case there was at most one slot element of each kind, resolveSlotsBeforeNodeInsertionOrRemoval is a no-op
-        and removeSlotElementByName would continue to operate in O(1). When there are multiple slot elements for a given
-        kind, we immediately enqueue slotchange event on the slot elements which newly became the first of its kind but
-        delay the enqueuing of slotchange event on the removed slot elements until removeSlotElementByName is called on
-        that element so that enqueuing of slotchange events on the slot elements still remaining in the in the tree would
-        happen before those which got removed as the DOM specification mandates.
-
-        Rename (https://dom.spec.whatwg.org/#shadow-tree-slots): In the case the slot element's name content attribute
-        is changed, the renamed element might have become the first of its kind or ceased to be the first of its kind.
-        There could be two other slot elements appearing later in the tree order which might have gained or lost assigned
-        nodes as a result. In this case, we invoke the algorithms for removing & inserting the slot with a key difference:
-        we enqueue slotchange event on the renamed slot immediately if it has assigned nodes.
-
-        To enqueue slotchange event in the tree order, this patch adds oldElement, which is a WeakPtr to a slot element,
-        to SlotAssignment::Slot. This WeakPtr is set to the slot element which used to have assigned nodes prior to the
-        node insertion, removal, or rename but no longer has after the mutation. This patch also adds a slot mutation
-        version number, m_slotMutationVersion, which is incremented whenever a node is about to be inserted or removed,
-        and slot resolution version, m_slotResolutionVersion, which is set to the current slot mutation version number
-        when the full slot resolution is triggered during slot mutations. They are used to avoid redundant tree traversals
-        in resolveSlotsAfterSlotMutation. This patch also makes m_needsToResolveSlotElements compiled in release builds
-        to avoid resolving slot elements when there is at most one slot element of each kind.
-
-        For insertion, oldElement is set to the slot which used to be the first of its kind before getting set to a slot
-        element being inserted in resolveSlotsAfterSlotMutation. We enqueue slotchange event on the newly inserted slot
-        element at that point (1). Since the slot element which used to be the first of its kind appears after the newly
-        inserted slot element by definition, we're guaranteed to see this oldElement later in the tree traversal upon
-        which we enqueue slotchange event. Note that if this slot element was the first of its kind, then we're simply
-        hitting (1), which is O(1) and does not invoke the tree traversal.
-
-        For removal, oldElement is set to the slot which used to be the first of its kind. Because this slot element is
-        getting removed, slotchange event must be enqueud after slotchange events have been enqueued on all slot elements
-        still remaining in the tree. To do this, we enqueue slotchange event immediately on the first slot element of
-        its kind during the tree traversal as we encounter it (2), and set oldElement to the previosuly-first-but-removed
-        slot element. slotchange event is enqueued on this slot element when removeSlotElementByName is later invoked via
-        HTMLSlotElement::removedFromAncestor which traverses each removed element in the tree order. Again, if this was
-        the last slot of its kind, we'd simply expedite (2) by enqueuing slotchange event during removeSlotElementByName,
-        which is O(1).
-
-        When the DOM invokes the concept to replace all children (https://dom.spec.whatwg.org/#concept-node-replace-all),
-        however, this algorithm isn't sufficient because the removal of each child happens one after another. We would
-        either need to resolve slots between each removal, or treat the removal of all children as a single operation.
-        While the DOM specification currently specifies the former behavior, this patch implements the latter behavior
-        to avoid useless work. See the DOM spec issue: https://github.com/w3c/webcomponents/issues/764

-        Populate "text/uri-list" with multiple URLs when the pasteboard contains multiple URLs
-        https://bugs.webkit.org/show_bug.cgi?id=188890
-        <rdar://problem/43648605>
-
-        Reviewed by Tim Horton.
-
-        Adds support for exposing a newline separated list of URLs via DataTransfer's "text/uri-list" type when pasting
-        or dropping multiple items on the pasteboard that can be represented as URLs. Currently on iOS, only the URL of
-        the first item (if present) is exposed, and on macOS, only the first out of all the URLs in the pasteboard is
-        exposed.
-
-        To fix this, we introduce `Pasteboard::readAllStrings`, which reads a list of pasteboard strings collected from
-        all available items on the platform pasteboard. Currently, this is only used to provide a list of URL strings
-        when fetching data for the "text/uri-list" type when calling `DataTransfer.getData()` and
-        `DataTransferItem.getAsString()`.
-
-        Tests:  DragAndDropTests.ExposeMultipleURLsInDataTransfer
-                UIPasteboardTests.DataTransferURIListContainsMultipleURLs
-                PasteMixedContent.PasteOneOrMoreURLs
-
-        * dom/DataTransfer.cpp:
-        (WebCore::readURLsFromPasteboardAsString):
-
-        Add a helper method that reads all URL strings from the pasteboard (for the MIME type "text/uri-list", which
-        corresponds to NSURLPboardType and "public.url" on macOS and iOS, respectively) and returns a single string
-        containing all non-empty URLs joined by newline characters. Also takes a filtering block which may be used to
-        reject URLs from being included in "text/uri-list" output.
-
-        (WebCore::DataTransfer::getDataForItem const):
-        (WebCore::DataTransfer::readStringFromPasteboard const):
-
-        Insteading of reading a single string from the pasteboard for "text/uri-list", call the above helper function to
-        read all URL strings in the pasteboard. If there are files present in the pasteboard, we also filter out URLs
-        whose schemes are not in the set of schemes that are safe to expose to the page (i.e. http(s), blob, and data).
-
-        * platform/Pasteboard.cpp:
-        (WebCore::Pasteboard::readAllStrings):

-        * platform/mac/PlatformPasteboardMac.mm:
-        (WebCore::typeIdentifierForPasteboardType):
-        (WebCore::PlatformPasteboard::allStringsForType const):
-
-        Add an implementation for `allStringsForType` on macOS. Unlike iOS, it's much trickier to get this right since
-        we need to maintain compatibility with legacy "NS*Pboard" types, and `NSPasteboardItem` can only provide data
-        for `NSPasteboardType`s (i.e. UTIs), so there's no way to just iterate through each pasteboard item and ask it
-        for data that matches the given type, if the types are not UTIs. However, in the case where we have multiple
-        items, the client must have used NSPasteboardWriting-conformant objects and/or NSPasteboardItem itself to write
-        data to the pasteboard. Since NSPasteboardWriting-conformant objects register modern pasteboard types when
-        writing to the pasteboard, we can simply iterate over these pasteboard items and ask for property lists using
-        type identifiers instead of having to worry about legacy pasteboard types. Furthermore, in the case where there
-        is only a single item in the pasteboard and we do need to handle legacy pasteboard types, using `-[NSPasteboard
-        stringForType:]` in the same way we do currently should yield the correct result.
-
-        As such, in the case where there is a single pasteboard item, we use `-[NSPasteboard stringForType:]` with the
-        original legacy type, and in the case where there are multiple items on the pasteboard, we iterate over each of
-        the pasteboard items and call `-[NSPasteboardItem propertyListForType:]` with the modern pasteboard type
-        corresponding to the given legacy pasteboard type.
-
-        The different corner cases in this logic are tested by the new API test, PasteMixedContent.PasteOneOrMoreURLs,
-        which exercises several different ways of writing one or more URLs to the pasteboard on macOS, which each result
-        in different legacy and modern pasteboard types being written to the pasteboard; our implementation of
-        `PlatformPasteboard::allStringsForType` on macOS handles all cases correctly.

-        Remove redundant inline text boxes for empty combined text

-        Reviewed by Zalan Bujtas.

-        whose composed string is empty as "redundant" just as we do for inline text boxes that have
-        a non-combined text renderer that have zero length so that we remove them. Such boxes are
-        visibly empty and do not take up space visually. By removing them we reduce memory and make
-        it easier to reason about the line box tree.
-
-        Currently RenderBlockFlow::computeBlockDirectionPositionsForLine() tests if an inline text
-        box is empty by checking if it has a zero length (InlineTextBox::len()). However an inline
-        text box associated with a RenderCombineText always has length 1 regardless of whether the
-        composed string it represents is the empty string. Instead we should expose a way to check
-        if an inline text box is visually empty and have RenderBlockFlow::computeBlockDirectionPositionsForLine()

-        Bug 182053 - [CSSOM View] Implement standard behavior for scrollingElement
-        https://bugs.webkit.org/show_bug.cgi?id=182053
-
-        Reviewed by Simon Fraser.
-
-        This commit introduces a new CSSOMViewScrollingAPIEnabled flag that will be used to implement
-        the standard behavior of DOM scroll* API as specified by the CSSOM View spec (see bug 5991).
-        It changes the behavior of document.scrollingElement so that it follows the spec when the
-        flag is enabled. This will allow to pass the WPT test cssom-view/scrollingElement.html when
-        it becomes the default behavior. WPT tests cssom-view/scrollingElement-quirks-dynamic*.html
-        still fail; comparing with Chromium's code, we might need to propagate the style of <html>
-        and <body> to the viewport element. Behaviors for other scrolling attributes will be changed
-        in follow-up bugs.

-
-        * dom/Document.cpp:
-        (WebCore::Document::isBodyPotentiallyScrollable): Helper function to verify whether the body
-        is potentially scrollable, as defined by the CSSOM View spec. It seems that
-        RenderObject::hasOverflowClip() may return incorrect value at this point and we might need
-        to do something similar to Chromium's style propagation to make it work. For now, we just
-        use the computed style. See bug 182292.
-        (WebCore::Document::scrollingElement): When CSSOMViewScrollingAPIEnabled is enabled, we
-        implement the algorithm of the CSSOM View spec.
-        (WebCore::Document::body const): Verify that the root is actually a <html> element or
-        otherwise return null. This is required by the CSSOM View spec and for WPT test
-        scrollingElement.html. It is consistent  with bodyOrFrameset().
-        * dom/Document.h: Add spec references for body() and bodyOrFrameset() and declare
-        isBodyPotentiallyScrollable().
-        * page/Settings.yaml: Add developer option for enabling the CSSOM View behavior.

-        [LFC][Floating] Block formatting context roots avoid floats.
-        https://bugs.webkit.org/show_bug.cgi?id=189150
-
-        Reviewed by Antti Koivisto.
-
-        This patch implements the float avoiding behaviour for block formatting context roots.
-
-        When a box establishes a block formatting context, floats from outside of the context can't interfere with content inside. In order
-        to achive this, such formatting root boxes need to be positioned so that they don't overlap with floats (floats that share the same
-        context with the formatting root). In ltr block direction, roots start with avoiding floats on the left, while in rtl on the right.

-        [Datalist] Display prefix-matched suggestions first
-        https://bugs.webkit.org/show_bug.cgi?id=189106
-
-        Reviewed by Tim Horton.
-
-        In order to increase suggestion relevancy, we should display suggestions that have
-        the same prefix as the input value first. In order to achieve this, we can place
-        the suggestions into two buckets, one that contains prefix-matched values and
-        another that contains only substring-matched values.
-
-        TextFieldInputType::suggestions() can be called up to three times before we
-        display the values. In order to avoid generating the same suggestions multiple
-        times, the most recent values can be stored and reused. We clear the cached values
-        whenever the datalist element is modified or when the suggestions view is hidden.
-
-        Finally, removed logic to de-duplicate the list of suggested values. This behavior
-        is not a part of the specification and leads to unnecessary slowdown when
-        populating the suggestions view.

-
-        In theory, WebCore::subdivide() should never return an empty vector - no subdivisions - as such a
-        result represents a programmer error. In practice, InlineTextBox can invoke WebCore::subdivide()
-        such that it returns an empty vector. One way this can happen is when subdividing an empty inline
-        text box associated with combined text (RenderCombineText). For now we add a check to bail out of

-
-        Reviewed by Darin Adler.
-
-        There is a chance that IDBDatabase::hasPendingActivity returns true.
-        The case that might happen is when stop() is called but there are still some active/being committed transactions.
-        In that case, hasPendingActivity will return true until these transactions get finalized.
-        While these transactions will probably be finalized at some point, it delays GC for no good reason.
-        And we might want in a follow-up patch to assert that ActiveDOMObject are GC-able whenever their context is stopped.
-        For that purpose, make sure hasPendingActivity returns false when context is stopped.

-
-        The look of the spelling dots on Mac and iOS are identical up to color. Towards making the
-        spelling dots in WebKit on iOS more closely match the look of the spelling dots in UIKit-
-        apps, standardize on using the same painting code for both Mac and iOS.
-
-        Currently iOS uses bitmaps to render the spelling dots and does not account for user/CSS
-        zooming. As a result, the spelling dots on iOS render with artifacts (e.g. truncated dots).
-        A side benefit of having iOS share the same painting code as Mac is that iOS will now paint
-        the dots programmatically and we avoid both the need to use bitmaps and fix the bugs in

-        Add support for dumping GC heap snapshots, and a viewer
-        https://bugs.webkit.org/show_bug.cgi?id=186416
-
-        Reviewed by Joseph Pecoraro.
-
-        Make a way to dump information about the GC heap that is useful for looking for leaked
-        or abandoned objects. This dump is obtained (on Apple platforms) via:
-            notifyutil -p com.apple.WebKit.dumpGCHeap
-        which writes a JSON file to /tmp which can then be loaded into the viewer in Tools/GCHeapInspector.
-
-        This leverages the heap snapshot used by Web Inspector, adding an alternate format for
-        the snapshot JSON that adds additional data about objects and why they are GC roots.
-        
-        The generated bindings code is changed to include the output root reason from isReachableFromOpaqueRoots(),
-        and to implement heapSnapshot() which provides the address of the wrapped object. A new IDL attribute,
-        CustomHeapSnapshot, is used to allow custom heapSnapshot() implementations for classes like JSDocument
-        that need to decorate the heap snapshot cell data with things like the document URL.
-
-        GCController registers a notifyutil callback which gathers the debug heap snapshot, and dumps it
-        to a file in /tmp. The file path is printed out to the system log.

-        Currently we assume that every marker has dictation alternatives (i.e. DocumentMarker::alternatives()

-        https://bugs.webkit.org/show_bug.cgi?id=188778
-
-        Reviewed by Brian Burg.
-
-        The original implementation of "instrumentation" breakpoints relied upon the frontend
-        sending somewhat arbitrary strings when enabling breakpoints for specific events. As an
-        example, setting a breakpoint for `requestAnimationFrame` expects `"animationFrameFired"`
-        as the string, which doesn't make much sense. This patch removes the usage of these strings
-        and instead expects the agent to implement a method that matches what is happening.

-
-        The inputmode attribute should apply to contenteditable elements, in addition to

-
-        Moved the inputmode attribute from HTMLInputElement.idl and

-
-        Also moved all logic to convert between the InputMode enum and string values
-        into InputMode.cpp to avoid exposing unnecessary details to WebKit. Furthermore,

-
-        Reviewed by Tim Horton.
-
-        Currently, attachment elements don't show up in the drag image snapshot on macOS. This is because only the
-        "Selection" phase is painted when generating a drag image on macOS, and many replaced renderers (with some
-        exceptions, such as RenderImage) only paint visible content during the "Foreground" phase. To fix this, we
-        override RenderAttachment::paintReplaced to paint the attachment in the case where the Selection phase is being
-        painted.

-
-        Reviewed by Carlos Garcia Campos.
-
-        Remove what's left of CoordinatedGraphicsLayerState usage in the
-        CoordinatedGraphics subsystem. In CoordinatedGraphicsLayer, this means
-        dropping the m_layerState member variable since at this point it is not
-        used anymore in any capacity. Affected helper methods and member
-        variables are also removed where possible.
-
-        The syncLayerState() method on the CoordinatedGraphicsLayerClient
-        interface is adjusted to not accept any parameters. Client should just
-        mark frame synchronization as required while the layer state is now
-        managed differently.
-
-        Instead of the CoordinatedLayerID (which is removed) the
-        Nicosia::PlatformLayer::LayerID alias is introduced as a layer ID type,
-        aliased to the uint64_t type.
-
-        CoordinatedGraphicsState.h file is rid of all structs except the
-        basic CoordinatedGraphicsState struct that at this point contains only
-        a reference to the Nicosia::Scene object. This will be further

-        Focus navigation order in slot fallback contents is wrong
-        https://bugs.webkit.org/show_bug.cgi?id=178001
-        <rdar://problem/42842997>
-
-        Reviewed by Antti Koivisto.
-
-        The bug here is that when a slot uses its fallback content, the fallback content's focus order doesn't get
-        grouped by that of the slot. Consider the following DOM tree:
-
-        - ShadowRoot
-            - div tabindex = 2
-            - slot tabindex = 1
-                - span tabindex = 3
-
-        In this example, the sequential focus navigation should be slot, span, then div. Even though span has tabindex
-        order of 3, which is lower than that of div, the fallback content of the slot should be grouped together
-        before the focus moves out of the slot content.
-
-        In WebKit, this concept of grouping elements for the sequential focus navigation ordering is implemeneted
-        as FocusNavigationScope. Both ShadowRoot and HTMLSlotElement are treated as a focus scope owner but we had
-        a bug that a slot element which uses its fallback content was not treated as a focus scope owner.
-
-        This patch addresses the bug by treating a slot wich uses its fallback content as a focus scope owner.
-

-
-        * page/FocusController.cpp:
-        (WebCore::isFocusScopeOwner): Treat a slot elment hs a focus scope owner regardless of whether it has assigned

-        (WebCore::FocusNavigationScope::firstNodeInScope const): Return the first child node when this

-        a slot element which uses a fallback content since the scope of a slot element is the parent scope. e.g. its
-        tree scope like ShadowRoot or Document inside which this slot element appears.

-        [CoordGraphics] Switch to Nicosia::CompositionLayer state tracking
-        https://bugs.webkit.org/show_bug.cgi?id=188693
-
-        Reviewed by Carlos Garcia Campos.
-
-        Populate Nicosia::CompositionLayer with additional LayerState member
-        objects. For now we're using pending, staging and committed states,
-        though it might be possible to narrow down these to just two.
-
-        Pending state contains state that will be moved to staging during the
-        final steps of the next layer flush. flushState() method accumulates all
-        state changes in the staging state, and also allows the caller to
-        additionally perform flushing operations that are specific to backing
-        store, image backing or content layer containers.
-
-        commitState() method moves staging state over into the committed state,
-        again allowing user to pass a functor that receives the just-committed
-        state and apply it to their composition engine.
-
-        Changes in state objects are done under a thread-safe lock. This might
-        not be completely necessary at this point, but will be useful when
-        additonal layer state updates will be coming from e.g. the scrolling
-        thread. It might also make sense to tie in this lock use with the
-        Nicosia::Scene lock in the future.
-
-        Nicosia::ContentLayerTextureMapperImpl is modified slightly to allow
-        determining during flushes whether an update is pending. This is
-        necessary for a special case in ThreadedCompositor where content (i.e.
-        platform) layers like WebGL or video require an additional level of
-        scene update coordination. This complete special case has to go through
-        another review to see whether it's still necessary. Ideally we would be
-        able to remove it.
-
-        CoordinatedGraphicsLayer is finally switched over to using
-        Nicosia layer objects for state updates of any kind. This patch only
-        adds all the necessary bits, but doesn't yet remove any of the existing
-        code (but rather disables it temporarily, before it's removed).
-
-        Updating of simple state values is already in place. For backing stores,
-        the flushCompositingStateForThisLayerOnly() method now takes care of
-        preparing the backing store object if necessary as per layer state,
-        while the updateContentBuffers() method is switched to operate with
-        TiledBackingStore objects now kept on the BackingStoreTextureMapperImpl
-        instance associated with that backing store. Helper methods like
-        adjustContentsScale() and createBackingStore(), only called from the
-        updateContentBuffers() method, are removed and the code there inlined.
-
-        For image-backed layers, the update is now done directly in
-        the flushCompositingStateForThisLayerOnly() method, if necessary. The
-        helper syncImageBacking() method is commented out in order to prevent
-        double-painting of image buffers for now, but all this (along with the
-        CoordinatedImageBacking logic in CompositingCoordinator) will be removed
-        later.
-
-        For layers backed by platform layer objects, integration is relatively
-        simple. setContentsToPlatformLayer() is changed to properly handle any
-        passed-in platform layer object, and updatePlatformLayer() invokes the
-        swapBuffersIfNeeded() method on the ContentLayerTextureMapperImpl object
-        during each flush, if necessary.
-
-        In order to ensure any Nicosia-specific state update properly triggers
-        a composition update, m_nicosia.performLayerUpdate is added and flipped
-        to true during the flush in case of any state change. This then triggers
-        a layer sync in the CompositingCoordinator object when the

-        Do not try to update the compositing policy when not in accelerated compositing mode
-        https://bugs.webkit.org/show_bug.cgi?id=188787
-
-        Reviewed by Simon Fraser.
-
-        RenderLayerCompositor::updateCompositingPolicy() is called very often (called from
-        RenderLayerCompositor::cacheAcceleratedCompositingFlags()) and it uses WTF::memoryFootprint() to decide the
-        current compositing policy. Getting the memory footprint is an expensive operation in Linux (and I suspect other
-        non-cocoa ports too), causing an excessive CPU usage. This caused the WPE and GTK+ unit test
-        /webkit/WebKitWebContext/uri-scheme to start timing out in the bots, because the test expects things to happen
-        fast and that's no longer the case. We could reduce the CPU usage a lot by not trying to update the policy when
-        not in accelerated compositing mode. We will need a solution for the accelerated compositing mode, though.
-
-        Fixes WPE/GTK+ unit test /webkit/WebKitWebContext/uri-scheme.

-        https://bugs.webkit.org/show_bug.cgi?id=188777
-
-        Reviewed by Simon Fraser.
-
-        Replaced boolean arguments and instance variables for modifier keys (ctrl, alt, shift, and meta keys) in
-        UIEventWithKeyState with OptionSet<Modifier> and isSimulated boolean in MouseRelatedEvent with IsSimulated
-        enum class.
-
-        Also made movementDelta always compiled instead of only when ENABLE(POINTER_LOCK) to simplify the code.
-
-        No new tests since there should be no observable behavioral change.

-        (WebCore::MouseEvent::initMouseEvent): Ditto.
-        * dom/MouseEvent.h:
-        * dom/MouseRelatedEvent.cpp:
-        (WebCore::MouseRelatedEvent::MouseRelatedEvent): Added a new variant which takes the minimum arguments
-        for gesture & touch events. In those events, detail is always set to 0, movementDelta is always set to 0,0,
-        and they are never simulated.
-        * dom/MouseRelatedEvent.h:
-        (WebCore::MouseRelatedEvent::IsSimulated): Added.
-        * dom/SimulatedClick.cpp:
-        (WebCore::SimulatedMouseEvent::SimulatedMouseEvent): Get OptionSet<Modifier> out of the underlying event
-        instead of manually setting each key state. This code now preserves the state of caps lock and alt-graph
-        keys but this is not observable because we have yet to implement getModifierState on MouseEvent.

-        (WebCore::UIEventWithKeyState::setModifierKeys): Added. Used by init*Event functions in subclasses. Note that
-        these functions preseve the states of alt-graph and caps lock keys to match the existing behaviors in this
-        cleanup patch but they don't match behaviors of Chrome or Firefox.
-        (WebCore::UIEventWithKeyState::modifiersFromInitializer): Added.

-        Shrink size of WebCore::Event further by reordering members
-        https://bugs.webkit.org/show_bug.cgi?id=188734
-
-        Reviewed by Daniel Bates.
-
-        Since WebCore::Event is ref-counted class, it has 4bytes m_refCount at the head of the class.
-        So placing 4bytes just after that before placing 8bytes aligned member (like pointers in 64bit
-        platforms) can save the size of WebCore::Event further.
-        This patch reorders members of WebCore::Event to shrink the size from 80bytes to 72bytes.

-        No behavior change.

-        Fixed the bug that HTMLElement's constructor was constructing an element of its own realm
-        instead of the realm of new.target. This results in the JS wrapper created for the element

-
-        In particular, step 9.2. specifies that we "perform element.[[SetPrototypeOf]](prototype)."

-
-        640x480x30fps is added as ideal constraints to getUserMedia if none other is added to provide consistent behavior.
-        Some cameras do not support 30fps as they have discrete frame rate ranges.
-        Before the patch, we were rejecting getUserMedia promise if the 'ideal' frameRate was not supported.
-        After the patch, we do not check whether frame rate is supported if it is not mandatory.
-        At capture time, we will still try to apply frame rate change and if not supported, the frame rate will not be set to 30 fps.
-
-        While we could surface discrete width/height/frame rate ranges, it seems best to fix the issue this way.
-        In the future, we might implement video interpolation for width/height/framerate at WebCore level.

-        The WICG is incubating a new proposal to allow clients to switch between streams
-        with different codecs within the same SourceBuffer. The proposal is being tracked
-        by <https://github.com/w3c/media-source/issues/155> and the proposed spec change
-        is available at <https://rawgit.com/wicg/media-source/codec-switching/index.html>.
-
-        Drive-by fix: One of the wpt tests uses a .mp3 file to test SourceBuffer switching.
-        The AVStreamDataParser does not necessarily emit every frame appended, and after a
-        new init segment is appended, it's possible that frames from the previous media
-        segment will be emitted. This causes an error condition to occur, due to an added
-        check in the spec for a new flag. When the SourceBuffer asks its private implementation
-        to reset the parser state, since there's no API on AVStreamDataParser to actually
-        reset the parser state, just set a flag to drop all emitted buffers until the next
-        initialization segment is parsed.

-        [Nicosia] Add Nicosia::ImageBackingTextureMapperImpl
-        https://bugs.webkit.org/show_bug.cgi?id=188550
-
-        Reviewed by Carlos Garcia Campos.
-
-        Add the Nicosia::ImageBackingTextureMapperImpl class, the
-        TextureMapper-specific implementation that will extend the ImageBacking
-        class.
-
-        This class will be used to contain and manage updates for layers that
-        are backed by image objects. The CoordinatedGraphicsLayer instance will
-        use the LayerState object to track the currently-presented image objects
-        and to store the latest update of these objects. The Update struct
-        contains information about the current visibility of the image in the
-        layer tree as well as the Nicosia::Buffer object containing the painted
-        image data that's to be presented on the screen.
-
-        During the layer flush the flushUpdate() method will move the current
-        update data into the pending position, from which this data will be
-        gathered by the composition component through the takeUpdate() method
-        and used to update the CoordinatedBackingStore object that's kept in
-        the CompositionState object on this impl class.
-
-        This will be deployed for use in the CoordinatedGraphicsLayer at a later
-        stage as it requires a larger rework in both CoordinatedGraphicsLayer as
-        well as the CoordinatedGraphicsScene classes.
-
-        The implementation itself differs from the current image backing support
-        in CoordinatedGraphicsLayer and CompositingCoordinator by abandoning the
-        idea of sharing single image backings between layers that might be
-        backed by identical Image objects. We thus end up trading any memory
-        consumption benefit in these scenarios for a much simplified
-        implementation. Overall this area needs more research both in figuring
-        out whether there's worthy improvements in grouping image backings, as
-        well as investigating whether it's possible to avoid additional image
-        rasterization by just leveraging direct pixel data via the
-        NativeImagePtr object.

-        [lFC][Floating] Add estimated margin top computation.
-        https://bugs.webkit.org/show_bug.cgi?id=188619
-
-        Reviewed by Antti Koivisto.
-
-        In order to figure out whether a box should avoid a float, we need to know the final positions of both (ignore relative positioning for now).
-        In block formatting context the final position for a normal flow box includes
-        1. the static position and
-        2. the corresponding (non)collapsed margins.
-        Now the vertical margins are computed when all the descendants are finalized, because the margin values might be depending on the height of the box
-        (and the height might be based on the content).
-        So when we get to the point where we intersect the box with the float to decide if the box needs to move, we don't yet have the final vertical position.
-
-        The idea here is that as long as we don't cross the block formatting context boundary, we should be able to pre-compute the final top margin.
-        (if this holds true for all the cases, the estimated prefix could be removed and just use marginTop() instead.)

-        connectedCallback is invoked by the HTML parser after child nodes had been inserted

-        Invoke the custom element reactions after constructing and inserting a custom element as specifed in step 3.3 of:
-        https://html.spec.whatwg.org/multipage/parsing.html#insert-a-foreign-element
-
-        The bug here was that HTMLConstructionSite::insertCustomElement uses attachLater so that even though the task
-        to insert the custom element was created, it didn't get executed until after CustomElementReactionStack in
-        HTMLDocumentParser::runScriptsForPausedTreeBuilder had been popped off of the stack.
-
-        Test: imported/w3c/web-platform-tests/custom-elements/parser/parser-sets-attributes-and-children.html
-
-        * html/parser/HTMLConstructionSite.cpp:
-        (WebCore::HTMLConstructionSite::insertCustomElement): Fixed the bug by manually executing the scheduled tasks.
-        This will enqueue any custom element reactions while CustomElementReactionStack in runScriptsForPausedTreeBuilder
-        is still in the stack.

-        Remove failing assertion introduced in r234873
-        https://bugs.webkit.org/show_bug.cgi?id=188581
-
-        * contentextensions/ContentExtensionCompiler.cpp:
-        (WebCore::ContentExtensions::compileRuleList):
-        The assertion is correct but failing because VectorTraits<String> is incorrect.
-        I'll re-add it and fix VectorTraits<String> in a separate patch.
