Describe the bug
When I activate Window Switcher for all apps, sometimes (if not always) some of my Finder tabs show up as separate windows in the list, and they are shown as invisible (with the eye next to them). These are not hidden, and I have no hidden windows in Finder. For some reason, I think Alt-Tab (another app) also has this same problem.
This would work if those Finder tabs are actually hidden, because I can just check “Exclude Hidden” for the Window Switcher, as you suggested. But these tabs are NOT hidden, and I actually WANT to see hidden windows normally, because “Hide” is my way of getting a window out of focus.
