Debugger: DevTools/Metro is disconnecting from the websocket if the app is backgrounded - was: `AppState.addEventListener('change')` on Android seems to suddenly stop working

Description

AppState.addEventListener('change' on Android seems to suddenly stop working.

Steps to reproduce

https://github.com/NorseGaud/expo-testing

npx expo run:android

Once up and running, background the app by switching to something like the Contacts app. Then, open a contact, create a contact, etc, and then come back. You won't see the active log. However, if you just background the app and don't do anything significant it will show active logs switching back.

Commencez par le reproducteur obligatoire sur github.com/NorseGaud/expo-testing et exécutez npx expo run:android. Mettez l’application en arrière-plan, utilisez une autre application, revenez, puis comparez les logs AppState avec la connexion websocket DevTools/Metro ; c’est terminé lorsque la mise en arrière-plan n’empêche plus les logs active attendus et ne déconnecte plus la connexion de débogage.
