ScrollView doesn't scroll to focused element

[Zahoq]

Environment

Android API: 28
Device: AndroidTV emulator and Xiaomi MI BOX
React Native: 0.61.5

Description

Sometimes ScrollView doesn't scroll to currently focused element on AndroidTV devices. Looks like issue is triggered because of two scroll events, one from ReactScrollView.java arrowScroll method and one from requestChildFocus. Issue seems to occur only when scrolling on the bottom of ScrollView.

React Native version:

"0.61.5"

Steps To Reproduce

1. Navigate with keyboard/remote controller up and down on between last rows of ScrollView.

Expected Results

Scroll follows focused element

Snack, code example, screenshot, or link to a repository:

App.ts example:

import React from 'react';
import {View, StyleProp, TextStyle, ViewStyle, TouchableOpacity, ScrollView, Text} from 'react-native';
const styles: {[name: string]: StyleProp<ViewStyle> | StyleProp<TextStyle>} = {
  container: {
    position: 'absolute',
    width: '100%',
    height: '100%',
    backgroundColor: '#000',
    justifyContent: 'flex-end',
    alignContent: 'center'
  }
};
const rows = [1,2,3,4,5,6,7,8,9];
const columns = ['a', 'b', 'c', 'd', 'e', 'f'];
type Props = {
  text: string;
  number: number;
}
const MyButton = (props: Props) => {
  return (
    <TouchableOpacity
      style={{width: 200, height: 200, margin: 50, backgroundColor: `rgba(100,255,0,0.3)`}}
      key={props.text + props.number}
      onPress={() => {}}
    >
      <Text>{props.text + props.number}</Text>
    </TouchableOpacity>
  );
};
const App = () => {
  return (
    <View style={styles.container}>
      <ScrollView>
        {rows.map((number) => (
          <ScrollView
            horizontal={true}
            key={'scrollview' + number}
          >
            {columns.map((text) => <MyButton text={text} number={number} key={text + number} />)}
          </ScrollView>
        ))
        }
      </ScrollView>
    </View>
  );
};
export default App;

ℹ️	It looks like you are using an older version of React Native. Please upgrade to the latest version, and verify if the issue persists. If it does not, please let us know so we can close out this issue. This helps us ensure we are looking at issues that still exist in the current release.

Android TV is not officially supported, though folks from the community have contributed code to enable it. I'm going to label this issue as something that would need to be fixed by a pull request from the community if needed.
