描述

### Current behaviour
- Open the Menu component
- The parent component re-renders
- Menu component closes and can't be opened again

### Expected behaviour
- Open the Menu component
- The parent component re-renders
- Menu component stays open

### How to reproduce?
```TSX
import React, {useState} from 'react';
import {View} from 'react-native';
import {Button, Menu, PaperProvider} from 'react-native-paper';

const MyComponent = () => {
const [randomVarialbeToForceRerender, setRandomVarialbeToForceRerender] =
useState(0);
const [visible, setVisible] = useState(false);

const openMenu = () => {
console.debug('Opening menu');
setVisible(true);

/**
* We update a state variable to force a re-render of the component.
* A real-world example could be a network request or some other
* asynchronous operation that updates the state.
*/
setTimeout(() => setRandomVarialbeToForceRerender(Math.random()), 1000);
};

const closeMenu = () => {
setVisible(false);
console.debug('Closing menu');
};

console.debug('visible', visible);
return (


Show menu}>
{}}
title={`Random ${randomVarialbeToForceRerender}`}
/>



);
};

export default MyComponent;
```

### What have you tried so far?
Memoization to avoid re-rendering the menu. However, this approach is limited and breaks
when the menu items are non-static (c.f. example)

调研方向

从 Menu 组件开始,使用 TypeScript 示例重现该问题:打开菜单,触发父组件重新渲染,然后尝试再次打开它。跟踪该重新渲染期间组件的状态和锚点行为;完成的标准是菜单保持打开,并且更新后仍然可以再次打开。
