I was able to reproduce only when the new user email was existing before enabling email as username.

1. Create a user with some email address
2. Enable "user email as username"
3. Create a new user with the same email as step 1
4. Try to login as that new user.

I think the solution here is to prevent creating the user if that email is already in use previously.

In order to fix this issue properly, we need to handle a few scenarios:

1. When enabling "required unique emails (currently no UI for this), the system needs to check if there are any existing duplicate emails and block the action if it's the case
2. Before being able to turn on "use email as username", "require unique emails" needs to be already turned on and the site restarted.
