Always on top fails when minimizing fullscreen window

[Hawkwing]

1. Make a window (window 1) always on top
2. Place another window (window 2) underneath window 1
3. Set another window to fullscreen (not maximized, use an application like Chrome that has a fullscreen mode) so it covers the same screen window 1 and 2 are on
4. Minimize the fullscreen window
5. click window 2

or
4. Close the fullscreen window

The result is that window 2 covers window 1 rather than staying underneath it.

That's a window manager error, rather than X.org.
