The KDE panel. It should stay in the same place (bottom of the viewport or
wherever) when the viewport is scrolled, but it might not be visible on all
desktops (there might be different panels on different desktops). Apparently 
people use this kind of feature, don't look at me, I use Gnome  ;)

I think the use of the word "sticky" has introduced confusion. The "no scroll"
hint does not imply anything about multiple desktops. The "all desktops" hint
does not imply anything about scrolling. If an application sets one hint OR
the other, its window can disappear under certain circumstances. If its sets
both, its window will always be visible in the same position on screen.
