Firebase storage 403 on delete

### Version info

**Angular:** 14.1.0

**Firebase:** 9.6.10

**AngularFire:** 7.4.0

**Other (e.g. Ionic/Cordova, Node, browser, operating system):**
Mac
node 16.16.0
Chrome latest

### How to reproduce these conditions

**Failing test unit, Stackblitz demonstrating the problem**

**Steps to set up and reproduce**

**Sample data and security rules**

private _getImagePath(): Observable {
return of('debug/users/%USERID%/images/exportimage'); //For demo purpose
}

// Succeeds
setImage(data: Blob): Observable {
return this._getImagePath().pipe(
switchMap(path => new Observable(obs => {
this.storage.ref(path).put(data).then(x => {
obs.next(x);
obs.complete();
});
}))
);
}

// Succeeds
getMetadata(): Observable{
return this._getImagePath().pipe(
switchMap(path => this.storage.ref(path).getMetadata())
);
}

// Succeeds
getUrl(): Observable{
return this._getImagePath().pipe(
switchMap(path => this.storage.ref(path).getDownloadURL())
);
}

// fails
deleteImage(){
return this._getImagePath().pipe(
switchMap(path => this.storage.ref(path).delete())
);
}

I get the same result from `this._storage.storage.refFromURL(url).delete()`

rules:

service firebase.storage {
match /b/admob-app-id-5092275243.appspot.com/o {
match /debug/users/{userId}/images/exportimage {
allow read: if request.auth.uid == userId;
allow write: if request.auth.uid == userId &&
request.resource.size < 1 * 1024 * 1024 &&
request.resource.contentType.matches('image/.*');
}

match /release/users/{userId}/images/exportimage {
allow read: if request.auth.uid == userId;
allow write: if request.auth.uid == userId &&
request.resource.size < 1 * 1024 * 1024 &&
request.resource.contentType.matches('image/.*');
}
}
}

### Debug output

** Errors in the JavaScript console **
FirebaseError: Firebase Storage: User does not have permission to access 'debug/users/L7vT58BkdXQTHa6nF3hNgHVeHcq1/images/exportimage'. (storage/unauthorized)

** Output from `firebase.database().enableLogging(true);` **

** Screenshots **

### Expected behavior

The image should be deleted

### Actual behavior

403 unauthorised

Comienza con los ejemplos deleteImage() y refFromURL(url).delete() y, después, inspecciona las reglas de seguridad de Firebase Storage mostradas en el informe. Reproduce el 403 con las versiones indicadas de Angular, Firebase y AngularFire y determina qué comportamiento debería permitir la eliminación; se considera terminado cuando la eliminación se realiza correctamente con las reglas documentadas o se demuestra que el problema se debe a la configuración.
