This makes us forget tracks at the right times. The spec also says no removetrack events should be fired because of this, yet it seems to be something other user agents do: https://wpt.fyi/results/media-source/mediasource-avtracks.html This is of low importance however, since MediaTracks are prefed off by default.

// in the list if we play from here, and no tracks should be removed from
|
|
// the list after we seek to the end.
|
|
// 4. Unsetting the media element's src attribute should remove all tracks.
