OSX: Zoomed-in behaviour while using cursor keys to move an object - the whole screen moves.

hi, i'll just leave this animated gif here..

steps to replicate:

1. Zoom in using OSX Purr Data Version 2.1.2 (20170322-rev.6f652fef)
2. Select an object
3. Use cursor keys on laptop to move object up
4. Notice that both the object moves up and the zoomed in screen move up
5. Post on purr-data issues :)
