Universal Autofill doesn't fill into menu bar pop-ups

Just as note here Quick Access can't seem to autofill into apps that are menubar items. If the menubar item uses a popover and you need to enter a password say into a VPN (experienced this today). Quick Access won't or can't fill into it. Also doesn't indicate in anyway it didn't work either.

However, VPNs mark these fields as a password box and you get Native Autofill suggestion. In this situation you have to resort to copy and pasting.
