Mac drag-and-drop questions

If changing the default behavior makes it consistent with native apps on 
macOS and with JavaFX apps on other platforms, then it seems like the 
right thing to do. We would want a CSR for the behavior change

As for your question about finding the bug using the old "RT-NNNN" bug 
ID, you can just paste that into the search box. It will redirect to the 
right bug:

https://bugs.openjdk.java.net/browse/RT-31449 --> 
https://bugs.openjdk.java.net/browse/JDK-8116268

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.
