[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>

Screenshots and Videos

You can see that the last added TextInput doesn't correctly focus on last item:

Start with the mandatory reproducer at github.com/freeboub/bug-react-native-Append-TextInput-In-ScrollView and run the provided ScrollView, Pressable, and TextInput example on Android 0.81.0. Compare the focus and scroll behavior with iOS and determine the conditions under which the newly appended, off-screen TextInput is not reached; done means the behavior is reliably correct on Android.
