ScrollView doesn't scroll to focused element

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;

In gif below i navigated up and down only:

从 ReactScrollView.java 开始，尤其关注报告中描述的 arrowScroll 和 requestChildFocus 方法。使用提供的 App.ts 示例，在 AndroidTV 模拟器或 Xiaomi MI BOX 上通过在最后几行之间移动来复现该问题。完成的标准是：在底部附近上下移动时，ScrollView 始终跟随获得焦点的元素。
