[iPad] Vimeo video goes black navigating from PiP back to full screen
https://bugs.webkit.org/show_bug.cgi?id=255145
rdar://107592139
Reviewed by Per Arne Vollan.
Vimeo gets into a state where it attempts to enter Element Fullscreen while the
video
is in picture-in-picture, which causes PiP mode to exit, returning the video to
the newly
fullscreened page. This video is simultaneously made "standby", i.e., it will
enter PiP
when the browser is "swiped" to the background. This causes the state machine
of the
VideoFullscreenInterfaceAVKit to get confused, as it's exiting one mode (PiP)
at the
same time as it's entering another (standby).
This is the most minimal change which will un-break this path, however there
remain
a few usability issues afterward. Because the WebContent process issues both a
enter-
fullscreen and exit-fullscreen command, it gets stuck in a state where it
thinks its
still animating into (or out of) fullscreen and doesn't allow any new
fullscreen mode
changes to be issued. This has the effect of preventing the video element from
going
into PiP or native fullscreen mode again.
