Text renders 1px bigger than View when explicitly given the same height with a specific combination of height and pixel ratio.

Description

Explicitly setting height: 15 on a parent View and child Text on a device with a pixel ratio of 3.5 (Pixel 7 Pro emulator) causes the child Text to render 1 px bigger than the parent View due to rounding in Yoga. When the Text is given a small border (borderWidth: 0.5) the bottom of the border is clipped by the parent View. This only happens with a certain offset from top - achieved for example by setting marginTop: 295.

There are several values and combinations of height and pixelRatio that give this result. I've only observed this on Fabric, on old architecture it renders the same.

Steps to reproduce

1. Enable new architecture
2. Use the following code:

const print_height = (layout: LayoutRectangle, component: string) => {
  const {height} = layout;
  console.log(`${component}'s height = ${height}`);
};

const TestApp = () => {
  return (
    <View
      style={styles.View}
      onLayout={event => print_height(event.nativeEvent.layout, 'View')}>
      <Text
        style={styles.Text}
        onLayout={event => print_height(event.nativeEvent.layout, 'Text')}>
        kkkkkkkk
      </Text>
    </View>
  );
};

const styles = StyleSheet.create({
  View: {
    justifyContent: 'center',
    alignItems: 'center',
    overflow: 'hidden',
    height: 15,
    marginTop: 295,
  },
  Text: {
    fontSize: 8,
    overflow: 'hidden',
    height: 15,
    borderWidth: 0.5,
    borderRadius: 4,
  },
});

3. Run on a device/emulator with pixelRatio: 3.5 (ex. Pixel 7 Pro)

Screenshots and Videos

该 issue 没有指出任何 repository 文件或测试。首先，在启用 Fabric 的 Android 设备或模拟器上使用 3.5 的像素比运行链接的 reproducer，然后跟踪 Fabric/Yoga 路径中的布局舍入行为。当明确相等的 View 和 Text 高度保持相等，并且半像素边框在报告的 reproducer 中未被裁剪时，即表示完成。
