        [Qt] Sub-Frame content is not updated when scrolling in certain circumstances
        https://bugs.webkit.org/show_bug.cgi?id=50373

        Make sure that we invalidate the backing store when using TILED_BACKING_STORE
        and the page contains sub frames. This bug appears only when frame flattening is
        disabled and scrollable subframes.

        Original patch from Thomas Thrainer.

        * WebCoreSupport/ChromeClientQt.cpp:
        (WebCore::ChromeClientQt::invalidateWindow):
