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:

Comienza con ReactScrollView.java, especialmente con los métodos arrowScroll y requestChildFocus descritos en el informe. Reproduce el problema utilizando el ejemplo App.ts proporcionado en un emulador de AndroidTV o en una Xiaomi MI BOX, navegando entre las últimas filas. Se considera terminado cuando el ScrollView sigue de forma consistente al elemento enfocado al moverse hacia arriba y hacia abajo cerca de la parte inferior.
