GM_registerMenuCommand does not return any element

[Aphexus]

Using GM_registerMenuCommand

One cannot get any element that was right clicked on.

click { target: null, buttons: 0, clientX: 0, clientY: 0, layerX: 0, layerY: 0 }

Nothing is filled out.

E.g., If I want to add a right click handler on an element it would be nice to know what the RMB was actually clicked on(such as a link or image or whatever).
