you can do it off a menu (open as popup) but you can't do it "by hand" or from a netwebpage etc.
So your URL as listed will appear as a page, not as a popup.
this is because the whole notion of a "popup" is a complex one. It's not really "popping up", it's unhiding something that was always there, and then populating it with whatever it should contain.
It's a lot of work under the hood to make all this work - and it's not something that can easily be done with hand-code.
