Codes

import React from "react";
import { Text, View } from "react-native";
import { Header } from "react-native/Libraries/NewAppScreen";

function App(): JSX.Element {
  return (
    <View>
      <Header />
      <Text style={{
        fontSize: 16,
        backgroundColor: "red",
        marginTop: 200,
        alignSelf: "center",
        textAlign: 'center',
        fontFamily: "BarlowCondensed-Regular"
      }}>
        番号を変更
      </Text>
    </View>
  );
}

export default App;

Actual behaviour

The text does not align center and the content shows incomplete. It seems that it's cut off and moves down!

Expected behaviour

The text aligns center and the content shows complete. For example:

fontSize2

However, if I sets lineHeight: 20 like

<Text style={{
  fontSize: 16,
  backgroundColor: "red",
  marginTop: 200,
  alignSelf: "center",
  textAlign: 'center',
  fontFamily: "BarlowCondensed-Regular",
  lineHeight: 20, // here!
}}>
  番号を変更
</Text>

Everything works well on all devices! But I think we shouldn't always set lineHeight to avoid this problem. It should be a bug on Android. Any ideas or how to fix it using a efficient way?

At last, the font file(BarlowCondensed-Regular) can be downloaded via the link: BarlowCondensed-Regular.

Any help will be appreciated.

Línea de trabajo

Comienza reproduciendo el problema desde App.tsx con la fuente de android/app/src/main/assets/fonts en un dispositivo Android afectado, como el OPPO K9x 5G. Compara la renderización de Japanese Text con y sin lineHeight: el trabajo está completo cuando el contenido es completamente visible y está centrado sin requerir lineHeight.
