Bug description

This issue has been trouble on-and-off for a few years, but it's kind of difficult to describe (hopefully searchers find this) and reproduce, so I've procrastinated opening an issue.

may be related to #2596, I also tried describing here.

Basically, I use full-screen mode a lot (almost exclusively for apps that support it), particularly Firefox. Using QS (pop open, use QS, close and return to whatever full-screen app "behind" it) often then results in the fullscreen app being unable to regain focus -- it's visible, but clicking on it doesn't put it in the foreground, none of its UI elements (e.g. the address bar in Firefox) work. To regain focus, I have to swipe to another space or app, click into it, then swipe back to the first app.

It is intermittent. Just try to reproduce a few times and couldn't, but I've definitely seen it recently.

Steps to reproduce

1. Use an app in full-screen mode
2. Launch Quicksilver (which opens overtop, the full-screen app remains visible in the background throughout this process)
3. Use Quicksilver #TODO: to do what? I think it's often "show large text" "type text"... what else?
4. Close Quicksilver
5. The app from 1st step remains visible but no longer can be interactive with -- file menu, buttons, nothing works
6. Swipe to something else on a different Space (or a different fullscreen app), click on it, then swipe back, all is fixed

Expected behavior

The fullscreen app should regain clickability once QS is dismissed
