[bug][ios] 3.14+ breaks all ScrollViews/FlatList when inside a stack with fullScreenGestureEnabled

[hirbod]

Description

Hi @WoLewicki, I hold up to my promise to find every bug in RNS :D

After the update to 3.14.1 it is impossible to scroll in a view (ScrollView, FlatList etc) with fullScreenGestureEnabled.

The gesture recognizer takes total control and does not allow scrolling anymore. If you set fullScreenGestureEnabled: false, it works.

The problem does not occur with 3.13.1. I suspect the regression comes from #1370

Screenshots

3.13.1 (works)	3.14.1 (broken)

Steps To Reproduce

1. Create a Stack Screen with fullScreenGestureEnabled.
2. Add ScrollView inside of it and navigate to it
3. Try to scroll - impossible. The horizontal pop gesture kicks in

Expected behavior

Should not break scrolling. Also messes around with react-native-gesture-handlers activeOffsetY. If set to -20, 20, it does also not work anymore, had to change it to -5, 5.

Actual behavior

Scrolling impossible with fullScreenGestureEnabled
Breaks scrolling

Reproduction

Just drop the ScrollView inside a Screen with fullScreenGestureEnabled set too true. Since Snack does not Support 3.14.1, it's not a real repro.

Thank you for resolving this issue so quickly! @kkafar
Do you have an idea when we can expect a release with this fix?

@chazzaoui
We're planning to do the release tomorrow, as there are some more changes we want to introduce. But don't cling to this date, if we'll wind more issues there might be a slight delay.
