Dimensions reports wrong sizes on Chromebooks

Description

All values from Dimensions and useWindowDimensions are wrong when running Android apps on a Chromebook. The reported dimensions seem to match the size of the full Chromebook screen, not the actual window in which the app is running. As the app's window is resized, the reported dimensions do not change.

For now I was able to work around this issue by using useSafeAreaFrame from the react-native-safe-area-context package.

Steps to reproduce

To setup a Chromebook for debugging, follow this guide: https://developer.android.com/topic/arc/development-environment. Afterwards, follow these steps:

1. Run an Android app built with RN on a Chromebook in debug mode
2. If the app fills the full screen, resize it to not fill the screen
3. Add const { height, width } = useWindowDimensions() into any component and log the height and width
4. Note that the height and width values are wrong

Bonus:

1. Install react-native-safe-area-context
2. Add const { height: fHeight, width: fWidth } = useSafeAreaFrame() into any component and log fHeight and fWidth
3. Note that the frame height and width are correct and do not match the values from useWindowDimensions

Repro is trivial if you have access to a Chromebook

Comienza reproduciendo el comportamiento de Dimensions y useWindowDimensions en una ventana de Chromebook cuyo tamaño se pueda cambiar, y luego compara el frame que informan con useSafeAreaFrame de react-native-safe-area-context. Se considera terminado cuando la altura y el ancho informados coinciden con los de la ventana real de la aplicación y se actualizan cuando se cambia el tamaño de esa ventana.
