When we seek to the end of the video while the MediaSource is still in open state, the readyState move to HAVE_METADATA [1] as we have the new playback position not in any TimeRanges of HTMLMediaElement.buffered. Once MediaSource.endOfStream() was called the readyState should be moved to HAVE_CURRENT_DATA as currentTime is now at the end of the video [2] However, we do not update the readyState under those circumstances and we stay in HAVE_METADATA As such if play() is called, playback wouldn't start (for the video to then end end the ended event should be fired) and the waiting event would fire instead.
