@thebrianchen, it seems types don't work correctly with CollectionReference.

 const posts = await store
  .collection("posts")
  .withConverter({ toFirestore, fromFirestore })
  .get();

posts.forEach(doSomething);

The forEach callback takes a QueryDocumentSnapshot (not a DocumentSnapshot) and there's no way to get the T on that object. It's only on DocumentSnapshot.

Is this by design, can we fix this
