Is there something off with the meta name of this field? For some reason it does not behave like the log in form with regards interacting with 1Password. 

It's been miss behaving last several versions, can't remember when it started. 

Please could you provide more information on what you mean when you say misbehaving? Ive not noticed any issues myself, and also use 1password

hard to test until next update. when I click in the email field my usual site accounts are not listed I have to click in to password field to show my account credentials. (from 1password)

This is likely because you are in your admin CP and not on our site. So it would show yours usually unless you explicitly save it again as one of your own. I cant replicate anything happening differently to what I usually see this end.

I will check on this the next I have an update I can run this end, but I havent noticed it personally
