Seems like a reasonable suggestion.  The alternative is to define the ended
property as a direct synthesis of the current states of all MediaStreamTrack


Object.defineProperty(MediaStream.prototype, 'ended', {
  get: function() {
    return this.tracks.reduce(function(a, track) {
      return a && track.ended;
    }, true);
  enumerable: true,
  configurable: true

A consequence of this algorithm is that a MediaStream with no tracks is always
