Username input deletes characters

On /login page, the username value is sent via POST automatically after 500ms without changes. Then the value of the input is re-set to the value that was sent on POST.

If you are unlucky or slow and your keystrokes are timed after the POST and before de response, it seems like the input is deleting the last character. Watch me struggling while trying to write "jkl" as my grandma does:

I don't think we need automatic post on username input. Shouldn't we just delete htmx related functionality on this input?
