Description
## What did you do?
I am trying to use Hero to animate transitions into a screen that is rendered with UICollectionView with UICollectionViewDiffableDataSource, by calling apply snapshot (NSDiffableDataSourceSnapshot)
## What did you expect to happen?
To see the animation between the views that have matching hero ids
## What happened instead?
The screen appears with the hero fade only
On dismissing, the hero animations works perfectly (which removes the option that ids weren't defined properly, or any other setup issue)
From my investigation, if I add a delay of 2 seconds before presenting the screen, the animation works.
I also checked and saw that the the cells still didn't render when Hero tried to animate
Also, in another screen, that works with the same lifecycle exactly but without the diffable datasource, the hero animation works!
I also tried triggering apply snapshot without animations, or with the iOS 15 API (applySnapshotWithReloadData)
Is there a way to get this to work?
