[Site Isolation] Video in cross-origin iframe is sometimes not rendering
after navigating back
https://bugs.webkit.org/show_bug.cgi?id=323760
rdar://187019361
Reviewed by Sihui Liu.
When navigating back to a page with a cross-origin iframe, the drawing area will
in some cases
change, and we need to move PlatformCALayerRemote objects to the new context in
PlatformCALayerRemote::moveToContext. For the layer hosting to be set up
correctly, we need
to call the layerDidEnterContext method in RemoteLayerTreeContext that takes the
HTMLVideoElement as argument.
No new tests, since we currently don't have a way to verify that the hosting is
correctly set up.
