Actually, there is no such thing as "iconify to systray", it's a
trick, the application unmaps its window itself and adds its icon to
the systray (unlike real iconification which is standard, and managed
by the window manager).

When the window is shaded, the window manager sets the property
NET_WM_STATE_SHADED, unmaps the app window and displays only the title
bar.

Maybe that confuses the application because the app window itself is
unmapped when shaded, and therefore confuses the application logic for
iconify in systray.
