Backdrop blur missing in media controls bar on Sierra
https://bugs.webkit.org/show_bug.cgi?id=173451

Patch by Antoine Quint <graouts@apple.com> on 2017-06-16
Reviewed by Simon Fraser.

Source/WebCore:

On Sierra, we need to enforce a stacking context on controls bars to guarantee that
the backdrop filters on the BackgroundTint are applied correctly.

Test: media/modern-media-controls/controls-bar/controls-bar-stacking-context.html

* Modules/modern-media-controls/controls/controls-bar.css:
(.controls-bar):

LayoutTests:

Add a new test that checks that a ControlsBar establishes a stacking context.

* media/modern-media-controls/controls-bar/controls-bar-stacking-context-expected.txt: Added.
* media/modern-media-controls/controls-bar/controls-bar-stacking-context.html: Added.
