When connecting an Android device to an external display all Texts seem to collapse (the only exception is when a minHeight is forced) and Modals do not open in fullscreen.

Steps to reproduce

1. Make a fresh 0.84.1 install
2. Use the attached reproducer or create some Text and a Modal
3. Verify on physical device everything works as expected
4. Connect the device to an external display and choose Computer/Desktop mode
5. Open the app on the display and you should see all broken Texts and the Modal that is shown incorrectly

Screenshots and Videos

This is how the reproducer appears on device:

The Modal should look like this:

Attach the device to an external display and choose "Computer" or "Desktop" depending on your device:

Open the app and Text and Modals are broken in React Native 0.84.1:

Making the same test using React Native 0.73.1 everything looks fine:

React Native 0.84.1 で必須の Snack 再現手順から始め、Computer/Desktop モードで外部ディスプレイに接続された Android デバイスを使用し、0.73.1 と比較してください。そのモードでの Text と Modal に対する Android のランタイム動作を調査してください。完了の条件は、Text が通常どおりレンダリングされ、Modal が外部ディスプレイ上でフルスクリーンで開くことです。
