Can I turn off the pop up suggestion list for 'localhost' ?

During web dev I run 'localhost' testing and need to login a localhost test site. I don't want 1P involved with this login at all because I never want to use or save passwords in 1P for 'localhost'. How can I configure 1P so that it completely ignores 'localhost' domain. I don't want it popping up any suggestions. I don't want it offering to save any passwords.

I have added 'localhost' to the Browser ignore list in Preferences, but this doesn't work.
