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

Die Issue nennt keine Repository-Dateien oder Tests. Führe zunächst den verlinkten Reproducer mit aktiviertem Fabric auf einem Android-Gerät oder -Emulator mit einem Pixelverhältnis von 3.5 aus und verfolge dann das Verhalten bei der Layout-Rundung im Fabric/Yoga-Pfad. Als abgeschlossen gilt die Arbeit, wenn die ausdrücklich gleichen View- und Text-Höhen gleich bleiben und der Halb-Pixel-Rand bei der gemeldeten Reproduktion nicht abgeschnitten wird.
