I found a minor bug in 1Password. When I set the menu bar to hide automatically (via System Preferences -> General -> Automatically hide and show the menu bar), clicking on the 1Password mini icon in the menu bar causes the window to be shown behind the other icons. Here's a screenshot that shows the issue: https://imgur.com/Get6kjA
This doesn't happen when I use the Cmd-Opt-\ shortcut.
