Android: Keyboard gets closed immediately

## Environment
`"react-native-pager-view": "^6.1.2"`
`"react-native": "0.65.3"`
`"react-navigation": all packages 5.x.x`
`"react-native-screens": "3.4.0",` -> this is where usually this bug is solved but it didn't work for me

AndroidManifest.xml:
`android:windowSoftInputMode="adjustResize"` - I need this, otherwise adjustPan pushes the header as well when keyboard is opened

## Description
So after trying out many combinations and solutions, this is what I found.
Hope you can help me.

We have multi page apply form process.
This includes input on almost every screen.
Issue happens first time when I focus on input, it automatically closes.
I tried combinations when:

- Parent does not rerender and I only have 2 pages - It works as expected (but I will never have only 2 pages)
- Parent does not rerender and I there are more than 2 pages - keyboard opens and closes immediately
- Parent rerenders and I there are more than 2 pages - keyboard opens and closes immediately
- Tried with `collapsable` props, still the same

## Reproducible Demo

`viewPager?.current?.setPage(currentPage + 1)`

```

```

Inizia riproducendo il problema con le impostazioni indicate di React Native, react-native-pager-view e Android, utilizzando l’esempio PagerView a tre pagine e la chiamata a setPage. Confronta il comportamento della tastiera con adjustResize e le combinazioni di props segnalate; il lavoro è completato quando la tastiera rimane aperta al primo focus su un campo di input nel modulo multipagina.
