Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Use react-native init to create a new project.
2. Edit App.js with the following code

   import React from "react";
   import { Text, View, useWindowDimensions } from "react-native";
   
   export const App = () => {
     const { width, height } = useWindowDimensions();
   
     return (
       <View
         style={{
           width: "100%",
           height: "100%",
           alignItems: "center",
           justifyContent: "center",
         }}
       >
         <Text>{width > height ? "landscape" : "portrait"}</Text>
         <Text>{`width: ${width}, height: ${height}`}</Text>
       </View>
     );
   };
   

Expected Results

1. At the first time I rotate the simulator to landscape, it should display "landscape" instead of nothing happens.
2. At the second time the simulator rotates back to portrait position, it should render "portrait" on the screen.
3. At the second time I rotate from portrait to landscape, it should display "landscape" instead of "portrait".

It is not easy to show device orientation features in snack, I'll attach screen recordings below.

首先使用 useWindowDimensions() 在 App.js 中进行复现，并在 iPad 模拟器上通过在竖屏和横屏之间旋转来验证行为。确认每次旋转后显示的方向以及宽度/高度值都能正确更新；该 issue 未指定要修改的 React Native 实现文件或测试。
