Realtime Database - indefinite hold after calling get()

### Operating System

### Browser Version

### Firebase SDK Version

### Firebase SDK Product:

Database

### Describe your project's tooling

### Describe the problem

Hi guys,

I built a simple script in Typescript that reads from the Database and prints the result. Whenever I do that, the newly created process does not close.

I'm not sure if this is an intended behaviour

I also added the `admin.database().goOffline();` as mentioned in https://github.com/firebase/firebase-js-sdk/issues/6932#issuecomment-1385331994 but didn't work.

### Steps and code to reproduce issue

Run the following js code

```javascript
admin.initializeApp();
_test();
async function _test() {
const ref = await admin
.database()
.ref('YOUR_REFERENCE')
.get();
const start_data = ref.val();
console.log(start_data);
admin.database().goOffline();
console.log('end');
}
```

You'll see that even though the console prints 'end', the program doesn't actually stop.

If you simply run
```javascript
admin.initializeApp();
_test();
async function _test() {
console.log('end');
}
```

the program stops as intended

Reproduisez le script Admin Node.js fourni à l’aide de admin.initializeApp(), database().ref().get() et goOffline(), puis inspectez le chemin Realtime Database utilisé par l’Admin SDK. C’est terminé lorsque le processus se termine après la lecture et le log final sans nécessiter de contournement supplémentaire ; le payload ne nomme aucun fichier ni test du dépôt.
