// When an animation is cancelled it no longer needs further ticks from the

// animation attached to the timeline, the timeline will stop observing the
// refresh driver and there may be no subsequent refresh driver tick for
// dispatching the queued event.
//
// By calling UpdateTiming *after* removing ourselves from our timeline, we
// ensure the timeline will register with the refresh driver for at least one
// more tick.
