Hate panel interaction with window managers. Way to nullify it?

In xfce4-panel 4.10, there is the setting named "Don't reserve space on 
borders" :
"Normally, maximized application windows do not overlap the panel. 
Setting this option disables this behavior and allows the windows to 
stretch to the screen edge."

But with it enabled, the panel shows on top of a maximized window. You 
can see the window under the panel, but when you click on that area you 
interact with the panel, not the maximized window which is partially 
under it.

Maybe the z-order of the xfce4-panel is "wrong", I don't know.
