I've got the Show autofill menu on field focus option on, because it's generally very handy. It occasionally causes trouble on some poorly-designed websites.
If I try to buy a movie ticket on Cineplex.com (big Canadian movie theatre site with glitches and bad UX), they have an input box with a select box that toggles on focus. The autofill menu comes up on top, and then if I click outside to dismiss the autofill menu, it also closes the dropdown.
Before click: (notice no 1password icon shows in the field)
After click: (notice now a 1password icon is showing)
I can click through to the "suggestions" and find the "hide on this page," I guess, but it might be handy to be able to just hit the Escape key or something to just dismiss the one instance of the window rather than blacklisting the page or whatever the hide button does.
