Apparently I was wrong about using it in a profile Sandbox, it created Dessamator/Infobox from the page User:Dessamator/infobox when I tried to save a change in the user namespace. It seems to be hardcoded for the template namespace.

I think using a personal sandbox is part an average editor's workflow, and perhaps this should work.
