[Android] Texts and Modals are broken in Android Desktop/Computer Mode

[andrea-martinez-dev]

Description

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

MANDATORY Reproducer

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:

0841.mp4

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

0731.mp4

As additional info, at first I realized the behavior breaks on 0.83.0 too, I made a test on 0.73.1 because I happened to have an app still built on that version on my device and it seems to work correctly, so I can't tell precisely in which RN version things broke.
