Hedger Wang 8975bb8e70 didFocus event should fired after transition finishes.
Summary:
For now, we emit `didFocus` event before fully resetting the transition and
hiding the stale scenes, so handler for `didFocus` event does not get the right
scenes in place. We should emit the didFocus event after resetting the transition and
hiding the stale scenes.
