Performance Issues in Angular Fire 6.1 and higher

### Version info

**Angular:** 13.3

**Firebase:** 9.14

**AngularFire:** 7.2

### How to reproduce these conditions

Create a collection query using the compat mode matching a lot of documents. In our case the query matched 2500 documents. Use the `stateChanges` method on the query and subscribe to it.

Locally trigger an update on one of the documents matched by the query.

### Expected behavior

The listener should update in a performant manner when a state change is detected as was the case in Angular Fire 6.0.5

### Actual behavior

Angular Fire triggers a very long running task. In my scenario tasks lasted more than 4 seconds causing the application to freeze. This behavior can be observed on all versions of Angular Fire > 6.0.5

Empieza reproduciendo la consulta de colección en compat-mode con stateChanges y unos 2.500 documentos coincidentes; después, compara su comportamiento con AngularFire 6.0.5. La tarea estará terminada cuando se identifique y resuelva la tarea de larga duración, de modo que la actualización de un solo documento ya no bloquee la aplicación.
