Delay animator update on tiles change.

The executor seemed to update the animator before the QS panel
generated the new tiles, causing the misaligned titles. In case the
animation starts before that delay, we also request a lazy update that
will run when trying to animate.

Flag: None
Test: Manually, by editing tiles and slowly dismissing QS
