Comment 3 for bug 926359

describing it in single steps maybe clearer:

what I do:
- switch to a desktop that has 2 or more open windows
what happens:
- one of the windows on that desktop gains focus (a good thing)
what I do:
- hit alt-tab
what happens:
- the same window keeps focus (a bad thing, I would expect any of the other windows on the same workspace to get focus)
workaround:
press and hold alt-tab until the window switcher comes up, which does show all open windows and allow me to switch to another one. (this is *much* slower though)
