Issue with upgrading to angularFire 6.0.2 in combination with jest and ng10 #2549

angularFire 6.0.2
Angular 10.0.4
Angular cli: 10.0.3
firebase: 7.16.1

Other (e.g. Ionic/Cordova, Node, browser, operating system):
Tested with node 12, 13 and 14
OS: Windows

How to reproduce these conditions

So when upgrading from angularFire 6.0.0 to angularFire 6.0.2, the following jest unit test will start to fail. Nothing else is being touched, so I'm pretty sure it has something to do with the upgrade of angularFire.

See also these issues when I thought it had something to do with jest:

This test will fail with jest:

import { AngularFireModule } from '@angular/fire';

import { environment } from '../../../src/environments/environment';

import { FirestoreService } from '../../../src/app/core/services/firestore-service';

import { MatDialogModule } from '@angular/material/dialog';

import { database } from 'firebase';

import { NO_ERRORS_SCHEMA } from '@angular/core';
