Stunner - Unable to add a child node (containment) to a parent using the keyboard

1) Create Decision Service. 2) Create a Decision Node. Place the Decision Node outside of the Decision Service. 3) Select the Decision Node and move it into the Decision Service using your keyboard (i.e. don't use your mouse!!!) 4) Move the Decision Service around the canvas. Notice that Decision Node is not correctly anchored to the Decision Service.
