setPersistence in AngularFire _BrowserLocalPersistence cannot be invoked without 'new'` #3550
Description
Problem
The setPersistence method does not work when imported from @angular/fire/auth, leading to a TypeError. However, it works when imported from firebase/auth.

When using the import from @angular/fire/auth, the following error is encountered:
ERROR TypeError: Class constructor _BrowserLocalPersistence cannot be invoked without 'new'
Code Example
-
Non-functional:
import { setPersistence, browserLocalPersistence } from '@angular/fire/auth';
await setPersistence(this.auth, browserLocalPersistence); -
Functional:
import { setPersistence, browserLocalPersistence } from 'firebase/auth';
await setPersistence(this.auth, browserLocalPersistence);

Ran into the same issue and am following the same work around as described in this ticket.
BTW, here is the stackoverflow.com question from 3 years ago with the exact same problem and work around: https://stackoverflow.com/questions/69292778/angularfire-auth-persistence-cannot-be-invoked-without-new

Trying to write tests with the Firebase Emulator it seems that sign in can persist across tests. I hoped that setting
setPersistence(auth, inMemoryPersistence)would help, but it does not seem to.However I still experienced the issue mentioned above and the work around still at least executed the test suite.
Same issue as #3131
