[LinearMediaPlayer] Blank video frames seen before docking and after undocking
https://bugs.webkit.org/show_bug.cgi?id=276453
rdar://130425275
Reviewed by Jer Noble.
Two issues resulted in blank frames briefly appearing in an <video> element in
element fullscreen:
1. Just prior to docking, an LMPlayableViewController is presented that
obscures the web view.
Since this VC's presentationMode is immediately changed to
`.fullscreenFromInline` which hides the
web view's scene and presents a new fullscreen scene, we should hide the view
controller while it's
in `.inline` mode (by setting its root view's alpha to 0).
2. Right after undocking, when committing the staged
AVSampleBufferDisplayLayer, MediaPlayerPrivate
would call renderingModeChanged(), which calls
Element::invalidateStyleAndLayerComposition(). This
results in the <video> element briefly rendering a black frame. To avoid this,
changed
MediaPlayerPrivate to call renderingModeChanged() as soon as the
AVSampleBufferDisplayLayer is
staged, while the LinearMediaKit scene is still occluding the web view.
