[Android]: append TextInput inside ScrollView doesn't always scroll correctly to the new Item

Description

On android only, when user add a new TextInput inside a ScrollView, the scrollview is expected to scroll to the new added TextInput. It doesn't always work on android.

Note: I don't know the exact reproduction conditions, but it seems that the added item should be outside of the visible screen.

Steps to reproduce

Create a sample app with a list of inside a .
You should be able to append a new with a button to reproduce the issue.
When a new is added I expect the ScrollView scroll to the newly added

On android this is randomly working. On iOS, It always works.
I had the issue originally on 0.79, but I reproduce it on a react-native only sample on 0.81.0 (see linked repo)

Here is an extract of JSX code:

      <ScrollView>
        <!-- Append a new TextInput -->
        <Pressable onPress={() => {
          setCount(c => c + 1);
        }}>
          <Text>Press me</Text>
        </Pressable>
        <!-- display a list of textInput -->
        {Array.from({length: count}).map((_, i) => (
          <TextInput
            style={{ height:50 }}
            key={i}
            autoFocus={i === count - 1}>    <!-- ensure only the last item added has autofocus (this is also reproduced if autoFocus={true} )-->
              Item {i + 1}
          </TextInput>
        ))}
      </ScrollView>

github.com/freeboub/bug-react-native-Append-TextInput-In-ScrollView にある必須の reproducer から始め、Android 0.81.0 で提供されている ScrollView、Pressable、TextInput の例を実行します。フォーカスとスクロールの挙動を iOS と比較し、新しく追加された画面外の TextInput に到達できない条件を特定します。Android での挙動が確実に正しくなれば完了です。
