Describe the bug
When logging into Authentik system using "default-authentication-flow", iCloud Keychain does not recognize the presence of the "username" field (stage authentication-identification). Only at the next stage, when detecting a user, it detects that he has a password stored in the database for this site and allows to use the key (stage authentication-password).

To Reproduce

1. Open Authentik login page (example: auth.example.com)

Expected behavior
iCloud Keychain detects that the username field corresponds to the username in the database for that portal and allows you to enter it (after authentication, e.g. with your finger or computer password), redirecting you to the next step of the form allowing you to enter your password further.
