FireFox not asking for device authentication when filling the passwords

I am on macos 14.5, and Firefox 128.0

I have enabled "Require device sign in to fill and manage passwords.". Which should ask for device authentication when I try to do anything with the saved passwords. And it does that when I go to "My passwords" and try to access them.

But, it doesn't ask for device authentication when I am using saved passwords on login forms. Is this intended? Anyone can go to the login form, fill the saved password without authentication and then see it.

I have attached an image and here is a screen recording of it of it - https://streamable.com/orf1gj
