Incorrect thumbnail size in edit mode

Attention, this might be hard to reproduce.

1. synchronize a significant number of media.
2. click edit.
3. scroll down until the table view needs to spawn new cells that weren’t displayed before.
4. in the new cells, the thumbnail size will be wrong.
5. reloading the view by leaving the app and reentering the app will fix the thumbnail size.

This is with the 2nd beta on iPhone 8 with iOS 12.latest.
