Why are user credentials in Custom Auth not hidden after saving?

Hey! Why are the credentials not hidden after saving when I use Custom Auth?

For example, if I use Header Auth, the credentials are hidden under the placeholder.

Is it bug for Custom Auth or not?

This is expected behaviour, since the input field is not really an input field but a

element which does not support the type=password mode like real HTML input fields.
