Rick Eyre 47acea1989 Bug 972479 - TextTracks added to a TextTrackList through an HTMLTrackElement should dispatch 'onaddtrack' event. r=rillian
The problem was that the HTMLTrackElement calls a different
AddTextTrack method then the HTMLMediaElement does when
addTextTrack is called on it. This patch has the method
that the HTMLTrackElement calls dispatch the onaddtrackevent
as well.
