Attempt to get a record from database without an in-progress transaction

### Version info

**Angular:** 14.2.8

**Firestore:** 9.15.0

**AngularFire:** 7.5.0

**Ionic:** 6.1.9

**iOS:** 16.1.1 iPhoneSE (error also happens on newer versions)

### How to reproduce these conditions

**Steps to set up and reproduce**

* Setup of `app.module.ts`:
```typescript
// ...
import { initializeApp, provideFirebaseApp } from '@angular/fire/app';
import { AngularFireAuthModule } from '@angular/fire/compat/auth';
import { FirestoreService } from './services/firestore.service';
import { AngularFireModule } from '@angular/fire/compat';
import { AngularFirestoreModule } from '@angular/fire/compat/firestore';

@NgModule({
declarations: [
AppComponent // ...
],
imports: [
// ...
IonicModule.forRoot(),
// ...
AngularFireModule.initializeApp(environment.firebase),
AngularFireAuthModule,
AngularFirestoreModule.enablePersistence(),
provideFirebaseApp(() => initializeApp(environment.firebase)),
],
providers: [
FirestoreService,
// ...
],
bootstrap: [AppComponent],
})
export class AppModule {}

```
* sync build to ios device
* lock screen (it's hard to actually reproduce)

### Actual behavior

After the screen gets locked on an iOS device, Firestore gets into an unexpected state and none of the Angular routes that use firebase queries can be accessed anymore. We only query data of our firebase instance, so there shouldn't be transaction issues.

app.module.ts のセットアップ、特に AngularFirestoreModule.enablePersistence() から始め、画面をロックして iOS デバイス上で再現します。Firestore 9.15.0 のエラーを、影響を受ける Angular ルートおよび FirestoreService の使用状況と比較します。ロック解除後に内部エラーによって Firebase クエリとルートが使用不能なままにならなくなれば完了です。
