Is this change still needed?

You can revert this change now that we are using TransitionChanged instead of
TransitionStarted. (I'm not sure what other effects it will have; best to revert
it.)

+  NotifyTransitionStarted();
 
   transition_animation_.reset(new gfx::SlideAnimation(this));
   transition_animation_->SetTweenType(gfx::Tween::LINEAR);
