The test introduced in https://github.com/WebKit/WebKit/pull/28770 fails on mac. While checking the MediaPlayerPrivateMediaSourceAVFObjC code I couldn't find where MediaPlayer::playbackStateChanged() is called. It's done correctly in MediaPlayerPrivateAVFoundationObjC but the MediaSource player doesn't inherit from that one.
