maintainVisibleContentPosition incorrectly autoscrolls on ios

Description

What I want is for flatlist to maintain its position if the offset is larger than 10, otherwise automatically scroll to new content, so I am using the maintainVisibleContentPosition with values of { minIndexForVisible: 0, autoscrollToTopThreshold: 10, }. Now this works correctly on android but not on ios.

Here is a small reproducible or its snack:

import React, {useState} from 'react';
import {
  SafeAreaView,
  View,
  FlatList,
  StyleSheet,
  Text,
  StatusBar,
  Button,
} from 'react-native';

type ItemProps = {title: string};

const Item = ({title}: ItemProps) => (
  <View style={styles.item}>
    <Text style={styles.title}>{title}</Text>
  </View>
);

const App = () => {
  const [data, setData] = useState([1, 2, 3, 4, 5, 6, 7, 8, 9]);

  const addToTop = () => {
    setData([data[0] - 1, ...data]);
  };

  const removeFromTop = () => {
    const [_, ...rest] = data;
    setData(rest);
  };

  return (
    <SafeAreaView style={styles.container}>
      <FlatList
        maintainVisibleContentPosition={{ minIndexForVisible: 0, autoscrollToTopThreshold: 10, }}
        data={data}
        renderItem={({item}) => <Item title={`Item ${item}`} />}
        keyExtractor={item => item.toString()}
      />
      <Button title="add to top" onPress={addToTop} />
      <Button title="remove from top" onPress={removeFromTop} />
    </SafeAreaView>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    marginTop: StatusBar.currentHeight || 0,
  },
  item: {
    backgroundColor: '#f9c2ff',
    padding: 20,
    marginVertical: 8,
    marginHorizontal: 16,
    height: 480,
  },
  title: {
    fontSize: 32,
  },
});

export default App;

Steps to reproduce

1. Copy the repro above to some rn project
2. Scroll to half of the first element, then press addToTop, on android position will be maintained which is correct but on ios it autoscrolls.

Comienza ejecutando el Snack vinculado en iOS y Android y prueba maintainVisibleContentPosition de FlatList con las acciones add-to-top y remove-from-top. Sigue el comportamiento de FlatList alrededor del umbral indicado y verifica después que iOS mantiene el offset cuando está por encima de 10 y solo hace autoscroll cuando está dentro del umbral, igual que Android.
