Option of create multiple accounts for each identity provider not working as expected in Firebase Authentication

As you can see in the image below, I enabled the second option (Create multiple accounts for each identity provider)

enter image description here

Now this email [email protected] is already in Firebase Authentication and I already logged in using Google provider.

I want to create a new account with the same email in the above but with the email provider but it tells me email account registration unsuccessful. It will work without any problems if I delete the email that signed in via Google provider.

enter image description here

I expected it will create the same email without any problems because it is a different provider

Did I misunderstand anything?

For linking multiple providers to the same account, you don't use the create user method there is a link method for it:

https://firebase.google.com/docs/auth/web/account-linking

import { getAuth, linkWithCredential } from "firebase/auth";

const auth = getAuth();
linkWithCredential(auth.currentUser, credential)
  .then((usercred) => {
    const user = usercred.user;
    console.log("Account linking success", user);
  }).catch((error) => {
    console.log("Account linking error", error);
  });

Basically, the behavior is that the account is already created, and already logged on, and then you can link their existing account with a new provider.
