[iOS] CollectionView stops allowing scrolling when the keyboard is closed on iOS

[TrueMoniker]

Description

If the following conditions are met, the collection view will not scroll.

1. Running on iOS
2. The header and footer do not fully fit on the screen when the collection items are shown
3. All items in the collection fit on the screen
4. The keyboard is opened and then closed. This sometimes takes multiple tries.

Steps to Reproduce

1. Create a CollectionView
2. Add collection items that can all fit on the screen at once.
3. Create an item template for your items. Include an Entry with ReturnType="Done" so you can open and close the keyboard
4. Add a header and footer that is large enough to take up most of the screen
5. Run the app
6. Scroll the collection view so all collection items are displayed on the screen
7. Enter values into an entry.
8. Close the keyboard with the done key
9. Try to scroll
10. Repeat step 6-8. After a few times (typically 2-3), the CollectionView will not scroll.
