1Password locks secure entry, causing glitches with Alfred, Witch, and Karabiner-Elements

Setting aside the related issue I mentioned, here's the main problem in more detail. 1Password is open because I've used it in an ordinary way. After doing lots of stuff, maybe minutes or hours later (I haven't yet tracked that)--and perhaps even across lid closings--I go to use Alfred's snippets feature, which automatically changes designated patterns of typed text into the specific string associated with that typed pattern. In other words, Snippets are shortcuts for frequently typed text. When I type the Snippet's trigger, nothing happens, and opening the Alfred app, I see the message, "1Password seems to be preventing text expansion by locking secure entry." Other utilities like Witch and Karabiner-Elements also stop responding properly. The culprit is always 1Password locking this Secure Input resource, and I have no other app that interferes with those frequently used utilities in this way.

Because this lock out happens well after I've used 1Password, I'm guessing that 1Password holds onto a system resource past the time it should be doing that. In fact, I can't even cause this lock out to happen on purpose: 1Password and the other apps normally just automagically get along. It's just that sometimes 1Password seems to fail to release the system resource on its own (I would think it would at least time out), and the only way out of the glitch is to quit 1Password from its menu bar item. When this situation occurs, 1Password's menu bar icon usually (or always) shows a little lock (or something) at its bottom right.
