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

Comece reproduzindo a consulta da coleção no compat-mode com stateChanges e cerca de 2.500 documentos correspondentes; em seguida, compare seu comportamento com o AngularFire 6.0.5. A tarefa estará concluída quando a tarefa de longa duração for identificada e resolvida, de modo que a atualização de um único documento não congele mais a aplicação.
