[Android Experimental] [Android 15/16] single letter is cut horizontally

[atlj]

Description

On Android 15 and Android 16, if you enable the Experimental mode, if you render text with a single letter, it gets cut horizontally:

<View style={{ alignItems: 'center' }}>
  <Text style={styles.text}>1</Text>
  <Text style={styles.text}>2</Text>
  <Text style={styles.text}>3</Text>
  <Text style={styles.text}>4</Text>
  <Text style={styles.text}>5</Text>
  <Text style={styles.text}>6</Text>
  <Text style={styles.text}>A</Text>
  <Text style={styles.text}>B</Text>
  <Text style={styles.text}>C</Text>
  <Text style={styles.text}>❤️</Text>
</View>

// ...

const styles = StyleSheet.create({
  text: {
    fontSize: 50,
    lineHeight: 80,
    textAlign: 'center',
  },
});

Steps to reproduce

1. Render a <View> with alignItems: "center"
2. Render a child text with textAlign: "center", and an arbitrary lineHeight
3. Enable experimental mode
4. Run on Android 15 or Android 16
