On iOS 16.0+ is not possible anymore to tap on Stack's front children if the fist child in Stack is filled. To reach the overlapped children it's only possible by swiping left or right.

The issue is not reproducible on iOS 15 or older.

Steps to Reproduce

1. Execute flutter run on the code sample on a iOS >=16.0 device
2. Start VO
3. Tap on any widget inside the Stack widget.
4. Note that VO only focuses on the filled widget.

Expected results:
VO should be able to focus on all children in Stack.
