react-native-screens accidentally broke a subtle behavior of the edge swipe/interactive pop gesture recognition. In simple vanilla iOS app, the edge swipe is easily recognized even when touch is panning across a scroll view diagonally or while scroll view is in motion. Because RNS does not have a normal view/view controller hierarchy (or some other subtle reason), the pop gesture breaks.

RNS sets _controller.interactivePopGestureRecognizer.delegate = self; so it's not completely broken… but this subtle behavior was still broken, driving me bonkers over the past couple of years :)

I don't know the true root cause of this issue, this could require deeper changes to RNS, for the default native behavior to just work. Regardless, setting interactive pop gesture recognizer to recognize simultaneously with scroll view's pan gesture recognizer fixes popping, while setting it to fail by scroll view's pan recognizer fixes scroll view still moving together with the edge swipe.

@WoLewicki @kacperkapusciak I am not sure if this PR is the reason, but since 3.14.1 its impossible to scroll in any screen that has fullScreenGestureEnabled.
