[iOS] Keyboard goes outside screen bounds when navigation back via navigation.goBack()

Description

When navigating back via navigation.goBack() from a custom back button, the keyboard goes outside the screen bounds during the transition.

However, when navigating back using the native header back button, the keyboard stays within the screen bounds and behaves correctly.

Expected behavior: The keyboard should stay within the screen bounds when going back via navigation.goBack(), same as when using the native header back button.

Current behavior: The keyboard visually exits the screen frame when going back via navigation.goBack().

Screenshot 1

This issue occurs in both React Native and Expo, across all versions.

Steps to reproduce

1. Open a screen that has a TextInput
2. Tap on the TextInput so the keyboard appears
3. Tap the custom back button that calls navigation.goBack()
4. The keyboard goes outside the screen bounds during the transition

Acknowledgements

Yes

Start with the linked Expo Snack and reproduce the transition using a TextInput, a custom button calling navigation.goBack(), and the native header back button for comparison. Trace the navigation.goBack() and native header paths in react-native-screens, then verify that the keyboard remains within the screen bounds during the custom-back transition on iOS.
