[veillette]

I recently added dragBound to the drag listener. I suspect it may be related to it.

[samreid]

I added a guard for now, not sure if that is the best long term solution though. Tagging for phetsims/tasks#1106

[veillette]

Sam correctly identified the issue. CT has been quiet since. Closing
