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?

Starte zunächst das verknüpfte Beispielprojekt mit npm run android oder npm run ios und vergleiche anschließend das Verhalten mit und ohne den APP_INITIALIZER-Provider in app.module.ts. Untersuche die in AppComponent referenzierte Theme-Konfiguration und überprüfe, dass Theme.setMode() nach dem Neustart der App den ausgewählten Modus und den korrekten Wert von Application.systemAppearance() beibehält.
