[Sam Spilsbury <smspillaz@xxxxxxxxx>]

Public bug reported:

 
  Windows A, B and C map (placed on top), and must stack relative to each other
  
  Window A gets stacked beneath D (which is a panel),
  Window B should be stacked above A,
  Window C should be stacked above B,
  
  What happened was that updateAttributes would be called and
  request to put window B above A, which it was already above in
  CompScreen::windows, so that stacking request becomes a no-op. In this case
  we check if the window is pending a restack and then request to put it
  above the same window it was already a sibling to if findSiblingBelow found
  that to be the case.

This could case GIMP and Libreoffice to be stacked above panels in some
cases on startup, since those windows must be placed at the top of the
stack on startup, and if valid stack positions are not given to them by
updateAttributes because we filtered them out as no-ops, then they would
remain at the top of the stack.
