Window dimensions doesn't change for android split screen

Description

After upgrading react-native from 0.62.2 to 0.63.3 I've met an issue that when I use split screen on my physical android device the dimensions for window doesn't change. It remains the same if I open the app in fullscreen, or split it with other app so it takes 1/2 or 2/3 or 1/3 of the screen space. I cannot tell exactly what react-native version got this broken, but I did test it both on 0.62.2 and 0.63.3 versions once again, so I am confident about this being an issue on latest react-native version

React Native version:

Steps To Reproduce

I've left the code example down here, copy it and paste in App component of newly initializated react-native project on 0.63.3 version and try to open the app in fullscreen and split-screen, see the window height being the same(vertical split-screen).

Expected Results

Dimensions.get('window').height AND useWindowDimensions hook must return different results for app being resized by using split-screen, but it returns the same value on & on, but it works as expected in 0.62.2

Snack, code example, screenshot, or link to a repository:

  console.log('manual get height:', Dimensions.get('window').height);
  const {height} = useWindowDimensions();
  console.log('useWindowDimensions hook height:', height);

Reproduce el problema en un dispositivo Android usando los ejemplos proporcionados de Dimensions.get('window') y useWindowDimensions, comparando el comportamiento de pantalla dividida en React Native 0.63.3 con 0.62.2. Sigue los puntos de entrada de Dimensions y useWindowDimensions para identificar dónde difieren las actualizaciones del tamaño de la ventana; se considera terminado cuando ambas APIs informan de la altura redimensionada de la pantalla dividida.
