The issue was caused by the scroll handle taking a couple of frames to
update its offset correctly after calling
`ScrollHandle::scroll_to_top_of_item`. The fast fix is forcing 3 frames
to render back-to-back.

In the future, we should look into `ScrollHandle` and see if there's any
way to update its state outside of paint.
