This means your window manager does not support _NET_WM_STATE_STICKY.
Emacs only supports that method of making a frame sticky, and no others.

I guess Emacs could be made to send a _NET_WM_DESKTOP with the desktop
set to 0xffffffff when the window manager does not support
_NET_WM_STATE_STICKY, but it would be a lot of trouble.  Since you're
trying to make some sort of popup, does the `override-redirect' frame
parameter work for you?
