The window manager does not control the icons in the notification area; 
the applications do. Pidgin controls what happens when one clicks on the 
pidgin icon, Rhythmbox when one clicks on the Rhythmbox icon, etc.

Looking at the Rhythmbox source code, it appears that when one clicks 
the notification icon, it decides whether to show or hide the window by 
checking the window state flags like so:
state & (GDK_WINDOW_STATE_WITHDRAWN | GDK_WINDOW_STATE_ICONIFIED)
