TabView (react-native-pager-view) does not update inside RNN screen on iOS (index updates but UI does not change)

What happened?

When using react-native-tab-view (which relies on react-native-pager-view) inside a react-native-navigation (RNN) screen on iOS, tab switching does not work correctly.

The index state updates correctly (onIndexChange fires), but the visible tab does not change or snaps back to the previous tab.

What was the expected behaviour?

Tabs should switch correctly when index changes.

Was it tested on latest react-native-navigation?

• I have tested this issue on the latest react-native-navigation release and it still reproduces.

Help us reproduce this issue!

Create a clean React Native 0.77 project
Add react-native-tab-view and react-native-pager-view
TabView works correctly
Add react-native-navigation
Render the same TabView inside an RNN screen
Try switching tabs

In what environment did this happen?

react-native: 0.77.3
react-native-navigation: 8.7.4 and latest
react-native-tab-view: 4.0.5
react-native-pager-view: 6.9.1
Platform: iOS
New Architecture: enabled

Reproduce the issue in a clean React Native 0.77.3 iOS project with react-native-tab-view and react-native-pager-view, first standalone and then inside a react-native-navigation screen. Compare the TabView behavior with New Architecture enabled and use the reported package versions as the baseline. Done means onIndexChange updates the visible tab reliably without snapping back.
