Login Failed Notification on users with 2-Step

I have notifications setup to notify on admin user logins & failed logins.

If a user account has 2-step verification enabled, I get a failed login notification when the correct username/password is entered, then a sign-in notification after they have successfully entered their 2-step code.

Seems like it shouldn't be considered a failed login unless the username/password is incorrect, or if 2-step code is incorrect.
