Public bug reported: I've uncovered what I think is a bug in the way that gnome-shell implements Alt-Tab support. First, my understanding is that the current version of Alt-Tab is only supposed to select between windows in the current virtual desktop.
I accidentally uncovered this as follows. I moved a Firefox window (I have many open) from virtual desktop 2 to virtual desktop 1 using C-S-A-Up. Then, when I use Alt-Tab, I see 3 firefox windows as part of the 7 choices displayed. If I click on one of the other 2 firefox windows, it takes me down to virtual desktop 2. The window list for Alt-Tab in virtual desktop 2 doesn't include the firefox window in virtual desktop 1, so immediately doing Alt-Tab after the mistake doesn't reverse things.
