There is this disabled code:

> > +  // This must come after we've set up the Promise chain, since requesting
> > +  // computed style will force events to be dispatched.
> > +  // XXX For some reason this fails occasionally (either the player.playState
> > +  // check or the marginLeft check).
> > +  //checkStateAtActiveIntervalEndTime(player);

We should figure out why that is and decide whether it's expected or not.
