Using absolute positioning, when the parent element has padding, the width height of the current element is incorrectly laid out using a percentage layout

Description

/**
 * Sample React Native App

 *
 * @format
 */

import React from 'react';
import {
  SafeAreaView,
  ScrollView,
  StatusBar,
  useColorScheme,
  View,
} from 'react-native';

function App(): React.JSX.Element {
  const isDarkMode = useColorScheme() === 'dark';

  const backgroundStyle = {
    backgroundColor: '#eee',
  };

  return (
    <SafeAreaView style={backgroundStyle}>
      <StatusBar
        barStyle={isDarkMode ? 'light-content' : 'dark-content'}
        backgroundColor={backgroundStyle.backgroundColor}
      />
      <ScrollView>
        <View
          style={{
            backgroundColor: '#000',
            height: 300,
            paddingTop: 200,
            paddingLeft: 200
          }}>
          <View style={{
            position: 'absolute',
            // width height 100%会排除父元素的padding
            width: '100%', height: '100%', left: 0, top: 0,
            backgroundColor: '#666'
          }} />
        </View>
      </ScrollView>
    </SafeAreaView>
  );
}

export default App;

In the new architecture, I set the height to 100%, but its height is not equal to the height of the parent container, but will subtract the padding of the parent container

The same code appears inconsistent on the web side and can occupy all the width and height of the parent element

[ShaoGongBra]

I just closed the new architecture with 0.75.2 and got the same result, which cannot occupy all the height. However, in the previous version, I used 0.71, which was consistent with web performance at that time

hello
i think i can solve this issue but i an new to opensource. Can i start forking this project?

yes

[krishnendu-2003]

Can you guide me through the file structure of this project? In this directory will i find the app.js file and its other pages?

[krishnendu-2003]

[krishnendu-2003]

is it available inside the helloworld directory?

[ShaoGongBra]

is it available inside the helloworld directory?
The reproduced code is just these two sentences

<View
          style={{
            backgroundColor: '#000',
            height: 300,
            paddingTop: 200,
            paddingLeft: 200
          }}>
          <View style={{
            position: 'absolute',
            // width height 100%会排除父元素的padding
            width: '100%', height: '100%', left: 0, top: 0,
            backgroundColor: '#666'
          }} />
        </View>

@ShaoGongBra this doesn't look New Architecture related (at least from your reproducer), right? Like the same behavior happens on both Old and New Architecture

[ShaoGongBra]

这看起来与 New Architecture 无关（至少从您的复制器来看），对吧？就像旧架构和新架构上都会发生相同的行为一样

yes
