[macOS] REGRESSION(275831@main): Netflix can error out while scrubbing
https://bugs.webkit.org/show_bug.cgi?id=273306
rdar://126654352
Reviewed by Eric Carlson.
A race condition can occur where the MediaSource object in the WebContent
process
does not check the buffered ranges for the new currentTime after a seek, which
leads
to the readyState remaining at HAVE_METADATA, and the seeked event failing to
fire.
Ensure that the MediaSource checks its buffered ranges after a seek by adding an
explicit "seeked()" method to MediaSourcePrivateClient to be used when a seek
completes
in a MediaPlayerPrivate, to notify the MediaSource to revalidate its buffered
ranges.
To avaid adding a new race condition, call this new "seeked()" method from
MediaPlayerPrivateRemote, rather than from MediaSourcePrivateRemote, to ensure
that
the "official" time is fully updated before the MediaSource monitiors its
source buffers.
