### Describe your project's tooling

index.html with source tag.

### Describe the problem

[updateProfile](https://firebase.google.com/docs/reference/js/auth.md#updateprofile)'s signature indicates that `displayName` and `photoURL` both can accept `null`, but they can't, because if you pass `null` to either of them you get `FirebaseError: Firebase: Error (auth/invalid-json-payload-received.-/displayname-must-be-string).` or
`FirebaseError: Firebase: Error (auth/invalid-json-payload-received.-/photourl-must-be-string).` respectively.

### Steps and code to reproduce issue

Assuming you already have a `user1@test.com` with `123456` password

```
var result = await signInWithEmailAndPassword(auth, "user1@test.com", "123456");
var user = result.user;
await updateProfile(user, { displayName: null, photoURL: null });
```
