[firebase-crashlytics] Fatal errors aren't sent to Firebase console

Description

On Android, crashing the application with firebase().crashlytics().crash() at launch or on tap of a button doesn't seem to create a report and send it to the Firebase console.
However, non-fatal errors registered using recordError() are logged. Only fatal errors alone are not.

I tried using an emulator as well as a real device.

I didn't encounter this problem on iOS.

I used adb -d shell setprop log.tag.FirebaseCrashlytics DEBUG in order to debug with Android Studio Logcat window.

LOGCAT

When launching the app:

Then, I immediatly click on the crash test button:

This follows right after the RuntimeException occured and the error screen on in the app is still visible:

When I restart the app:

I noticed the user ID is missing when I restart the app. I don't know if it matters in this situation.

My app configuration (in app.ts):

firebase().initializeApp().then(() => {
  
  // other configurations for firebase modules

  //Crashlytics
  firebase().crashlytics().setUserId(device.uuid);
  firebase().crashlytics().setCrashlyticsCollectionEnabled(true);
  firebase().crashlytics().log('App started');
});

Start with the Crashlytics setup in app.ts and the firebase().crashlytics().crash() call shown in the report. Reproduce the fatal crash on Android, inspect the provided Logcat output, and compare it with the working recordError() path. Done means fatal reports appear in the Firebase console after the app restarts.
