Yeah, as currently written the drop behaviour is up to the target, so if 
the source provides a URL as the data, the desktop is likely to treat it 
as a request to create a link (and a browser window a request to navigate 
to that link).

In general the drag and drop section is intended for dragging and dropping 
data (as in copy and paste). For dragging of UI elements, I recommend 
using the mouse events. HTML5, CSSOM, or the DOM Events spec will probably 
gain a method to allow mouse capturing, so that you can determine whether 
the element is being dragged out of its container.
