Fix ScrollView automaticallyAdjustKeyboardInsets not resetting when P…

…refer Cross-Fade Transitions is enabled (#35933)

Summary:
Similar to the issue here #34503 but this is also happening if we just use `ScrollView` and `TextInput` with `automaticallyAdjustKeyboardInsets` enabled.

When we enable `Prefer Cross-Fade Transitions` in `iOS` we get a keyboard height of `0` which causes the inset/offset miscalculation and the content jumps up when the keyboard gets hidden.
