Relevant portion of the spec:

> Whenever a track in a VideoTrackList *that was previously not selected is selected*, the user agent must queue a task to fire a simple event named change at the VideoTrackList object. This task must be queued before the task that fires the resize event, if any.

Right now we fire events when a track is deselected also.

This is going to be hard to test for in WebKitGTK, since playbin won't let us completely turn video off (so setting selected = false just the video stream to whichever want playbin sicks). I'll probably do that first..
