Title:
  window spread not working with always on top

Status in Unity:
  Confirmed
Status in unity package in Ubuntu:
  Confirmed

Bug description:
  Greetings:

  I encountered an issue on my working install of 12.10 64-bit, and was
  able to replicate the issue on a fresh install on a virtualbox.

  In this bug, I will refer to window "spread" as the action achieved by
  clicking on a Unity Launcher icon when multiple instances of that app
  are already open.  I can't recall if that is the official name or not.

  I noticed that when I tried to spread an app's windows didn't work
  when one of the windows was marked as always on top.  I think I can
  confirm that this issue only occurs when a separate app is open and in
  between the current app's drawing stack order.  Consider a working
  example:

  I have a browser (chrome) open in the background with my email.  I
  open another application (TeXMaker...) to do some writing.  I open
  another browser window, make it small, and put it on the corner of my
  screen, set to 'always-on-top', to monitor something while I write.

  I then want to see my email window.  When I click the Unity Launcher,
  I expect the two browsers to spread so I can select my email instance.
  Instead, nothing happens.  The 'always on top' window stays on top,
  and the screen doesn't change.

  OK, so I tried on a fresh 12.10 install on a virtual box. 
  1. I open two nautilus windows.  I mark one as 'always on top'.  Click on the nautilus Unity launcher, and it spreads fine.
  2. Then I opened firefox. It opens in front of one nautilus and behind the 'always-on-top' nautilus window. 
  3. I click on the nautilus launcher again it no longer spreads. 

  I can provide any further information that would help.  I don't think
  it matters but I am running the x-swat nvidia driver, and I have been
  upgrading this installation since 11.04.

  Thanks!
