I quote:  "The topStack is the frontmost stack with the lowest mode."

The mode runs from 0 to 13 (unless someone's added some modes 
lately), and invisible isn't one of the modes-a toplevel visible 
stack has the same mode as a toplevel invisible one.

(I don't claim this makes actual sense, mind you....)
