IconMan: deiconify and warp to


I’ve the following line in my configuration of FvwmIconMan:

*FvwmIconMan: Action      Mouse   1 N sendcommand Focus, sendcommand "Iconify off", sendcommand "Raise", sendcommand "WarpToWindow 10p 10p"

So when I click on a button of a window, it should deiconify (if iconified) and warp the mouse pointer near the top left edge.
For non-iconified windows this works, but for iconified windows the pointer is warped to the place where the icon
was. What am I missing?
