Issue with APP_INITIALIZER and NativeScript Theme: Core V2

Environment

• Node.js: v16
• Android SDK: 30
• JDK 11
• Xcode: 13.3.1
• CocoaPods 1.11.2
• CLI: latest nativescript@8.2.2
• Cross-platform modules: @nativescript/core@8.1.5
• Android Runtime: @nativescript/android@8.1.1
• iOS Runtime: @nativescript/ios@6.5.5 (JSC!)
• Angular: @angular/core@13.2.5
• Plugin(s):
  ├── @nativescript/theme@3.0.2

Describe the bug
The Theme.setMode() from the NativeScript Theme plugin stops working when an async APP_INITIALIZER is used.

To Reproduce
Steps to reproduce:

• Clone the sample project
• run npm run android or npm run ios (the home component will show some theme/system appearance details)
• tap "Change app theme" and choose the opposite theme to your current device setting, the theme changes correctly for now, but
  Problem 1: as you can see Application.systemAppearance() now shows a wrong value (e.g. "dark", even if the device is in light mode)
• Close the app (not only put it to background)
• Restart the app ...
  Problem 2: The app theme is back to auto, although it is set to a specific mode in the AppComponent

But if you disable the APP_INITIALIZER by removing the APP_INITIALIZER from the providers array in app.module.ts everything is working just fine.

Expected behavior
Theme.setMode() is working despite the use of APP_INITIALIZER.

Additional context
My first suspicion was that something was amiss with the theme but then I could narrow it down to the APP_INITIALIZER.

Any thoughts? Help?

Commencez par exécuter le projet d’exemple lié avec npm run android ou npm run ios, puis comparez le comportement avec et sans le fournisseur APP_INITIALIZER dans app.module.ts. Inspectez la configuration du thème référencée dans AppComponent et vérifiez que Theme.setMode() conserve le mode sélectionné ainsi que la valeur correcte de Application.systemAppearance() après le redémarrage de l’application.
