Public bug reported:

If I have multiple windows of the same program spread across more than
one workspace, the application switcher gets confused when trying to
Alt-Tab between that program and some other program. When Alt-Tabbing,
the "first focus" (the left-most application/icon) in the switcher stays
on the program with multiple windows on multiple workspaces, despite
that this program was already focused when pressing Alt-Tab and thus
switching from it to another program practically requires another Alt-
Tab press.

Steps to reproduce:

1. Make sure you have at least two workspaces
2. Open two (2) Firefox windows in the 1st workspace
3. Move to 2nd workspace, and open one (1) Firefox window
4. Open Gedit
5. Alt-Tab once (focus changes to Firefox)
6. Alt-Tab again => on the switcher, Firefox is selected and switching to Gedit 
requires another Alt-Tab press

Firefox and Gedit were used as an examples: I could reproduce this with
any random program I tried.
