Add the ability to abort drag&drop by pressing ESC

Hello lammoth,

Thanks for your feature request.

While I can't make any promises, I can se where this be helpful to use the ESC key to cancel the drag function before the credential is dropped, may be accidentally to a window where you did not want the data exposed. I've passed your request along to the Product team for consideration.

Your feedback is greatly appreciated. If you have any other suggestions, just let us know!
