Multiline controlled input enters an infinite loop on iOS

Description

This code enters an infinite loop on iOS.

import React, {useState, memo} from 'react'
import {TextInput} from 'react-native'

let App = () => {
  console.log('render App')
  const [outlet, setOutlet] = useState(null)
  return (
    <>
      <Outlet outlet={outlet} />
      <Child setOutlet={setOutlet} />
    </>
  )
}
export default App

let Child = memo(({setOutlet}) => {
  console.log('render Child')
  const [value, setValue] = useState('')
  return (
    <Portal setOutlet={setOutlet}>
      <TextInput
        onChangeText={text => setValue(text)}
        value={value}
        multiline
        style={{
          backgroundColor: 'red',
          marginTop: 200,
        }}
      />
    </Portal>
  )
})

let Outlet = memo(({outlet}) => {
  console.log('render Outlet')
  return outlet
})

let Portal = memo(({children, setOutlet}) => {
  console.log('render Portal')
  React.useLayoutEffect(() => {
    setOutlet(children)
  }, [children])
  return null
})

Removing multiline prop fixes the issue.

I suspect this may be related to https://github.com/facebook/react-native/issues/36494 but who knows.

从链接的 rn-bug-loop 复现器开始，使用 issue 中所示的受控多行 TextInput 在 iOS 上复现无限循环。比较移除 multiline 后的行为，然后跟踪涉及的 React Native TextInput 路径；当受控多行输入不再循环且报告中的设置仍能正常工作时，即表示完成。
