Summary [MediaSource] ended event may not always fire when the duration change

Consider the following. a MediaSource is created with data from [0-5][6-10] playback stalls at currentTime = 5. Now the player removes data from [6-10] and set the duration to 5. The ended event will never fire as timeChanged would only be called at the completion of the seek handled by https://searchfox.org/wubkat/source/Source/WebCore/html/HTMLMediaElement.cpp#6060-6061 ``` if (now > dur) seekInternal(dur); ``` this causes the intermittent timeout in the test imported/w3c/web-platform-tests/media-source/mediasource-duration.html
