I'd like to see more detailed descriptions here in general, to explain what's going on and what's expected, in words. It makes it easier to understand the intent of the test code, and easier to confirm that this is what the test is doing, when some failure comes down the line. I was also confused by this sentence, because that's not what the code does.

Hence: "This test pauses the video, presses the fullscreen button, and drags the controls when the mouse is over a button. It should not move."

Same thing here, please (above, in line 9), except "... It should follow the mouse drag."

This made EWS fail on about half of patches submitted, failing two tests on mac-debug-ews:

New failing tests:
media/modern-media-controls/macos-fullscreen-media-controls/macos-fullscreen-media-controls-drag.html
media/modern-media-controls/macos-fullscreen-media-controls/macos-fullscreen-media-controls-drag-is-prevented-over-button.html

Rolling out.

Re-opened since this is blocked by bug 168882

[Antoine Quint]

This is due to MacOSFullscreenMediaControls not calling this._leftContainer.layout() in its layout() method.
