Firebase Database (${JSCORE_VERSION}) INTERNAL ASSERT FAILED: Unknown node type

### Version info

**Angular: 14**

**Firebase: 9.9.1**

**AngularFire: 7.4.1**

**Other (e.g. Ionic/Cordova, Node, browser, operating system):**

Node 16.13.0
macOS

### How to reproduce these conditions
#### Steps to set up and reproduce

When a local or production build is served, we have the below console error:
```
zone.js:1061 Unhandled Promise rejection: Firebase Database (${JSCORE_VERSION}) INTERNAL ASSERT FAILED: Unknown node type ; Zone: ; Task: setTimeout ; Value: Error: Firebase Database (${JSCORE_VERSION}) INTERNAL ASSERT FAILED: Unknown node type
```

Also, not sure if because above max call stack also showed:

```
polyfills.js:29650 Uncaught RangeError: Maximum call stack size exceeded
at ChildrenNode.isLeafNode (vendor.js:286427:13)
at ChildrenNode.equals (vendor.js:64135:22)

```

#### Source code from tracing:
```
/**
* Returns an Error object suitable for throwing.
*/
const assertionError = function (message) {
return new Error('Firebase Database (' +
CONSTANTS.SDK_VERSION +
') INTERNAL ASSERT FAILED: ' +
message);
};
```

### Expected behavior
Build runs on both local and production without errors

### Actual behavior
Build runs on both local and production has errors

Empieza reproduciendo las compilaciones local y de producción con Angular 14, Firebase 9.9.1, AngularFire 7.4.1 y Node 16.13.0. Rastrea el origen de assertionError de Firebase Database y el stack de ChildrenNode.equals mostrado en el informe. Se considera completado cuando ambas compilaciones se ejecuten sin el error de tipo de nodo desconocido ni la excepción de desbordamiento de la pila de llamadas.
