Mac drag-and-drop questions

As a heads up there are actually two behavior changes to be reviewed. JavaFX is picking up some archaic behavior from the OS which thinks that the modifier key for LINK is Control. The Finder switched over to Option+Command a long time ago and I think JavaFX should follow suit.
As for finding older bugs I guess it’s just a matter of using the right Search box (my bad). Thanks.

This doesn’t match the JavaFX behavior on Windows or the user interface guidelines of any platform; normally the default operation is MOVE and the user has to press Option to force COPY. This bug makes it impossible for a control to get drag-and-drop right on the Mac. The code was last touched to address RT-31449 but it looks like the default mode was COPY even before that.
