6.8.1 breaks the global back gesture

## Environment

iOS, RN 0.79.3, Paper and Fabric

## Description

Version `6.8.1` is a regression from previous versions. We have a pager view that contains multiple scrollviews, and on the latest version the back gesture from `react-native-screens` gets swallowed by the pager.

# Expected behaviour (`6.8.0`)

# Current behaviour (`6.8.1`)

The issue seems to be caused by https://github.com/callstack/react-native-pager-view/pull/933, which appears to be a fix for pagers inside of scrollviews. Unfortunately, it seems to break scrollviews inside pagers.
