My testing suggests that there's still source application specific behavior.
* Simple drag of images works when Safari or Chrome is the web browser.
* No combination of Option, Command, or Control seems to work in Firefox; the
drag behavior always produces a URL.
So I guess the patch partially fixes the regression. Given the state of the OS
X api I'm not sure what the best way forward is. I'd try and jump in to
contribute but I unfortunately have zero experience working with Objective C or
programming against Apple's APIs
Best,
Paul
