A page scale animation isn't explicitly involved in a commit after creation, so
this phrasing is a bit strange.  I'd say ", but we haven't notified the client
about it yet (this is delayed until after commit to give the scroll offset time
to fully stabilize)"

Done.

Please move this next to "pending_page_scale_animation_".

Done.
