setDragImage on dataTransfer of DragEvent
This has been overlooked sine IE 5.5, it has even made it way to the mobile IE (http://caniuse.com/#feat=dragndrop) but not the desktop one.
setDragImage is now in development and will appear in a future version of Edge.
It's almost 2018.

I support this request. I don't understand why this hasn't been implemented or even discussed.
The only resource online that I can find where it's mentioned is in an old 'connect Microsoft' feature request (https://connect.microsoft.com/IE/feedback/details/804304/implement-datatransfer-prototype-setdragimage-method) from August 2013 where the response was that this is by design.
The setDragImage method isn't even on the roadmap of features being considered for MS Edge (https://dev.modern.ie/platform/status/) as of October 2015.
Every other browser offers some type of support for this and unless I am missing something critical, I don't see why it is hard to implement?
