Expression editor tree widget selects wrong node

What steps will reproduce the problem?

1. Define query 'All pts who have 123397009|Injury of anatomical site|'
2. Try to change querydef:
   a. Double-click on existing criterion
   b. Click Edit button on Author Component Query dialog
   c. Enlarge Author expression dialog to reveal Expression Editor pane
   d. Expand the role group
   e. Double-click on the Associaed morphology = Damage line
   f. In Concept Hierarchy dialog, expand the 'Damage' line
   g. Double-click on 'Dislocation'

What is the expected output? What do you see instead?

Querydef changed to 'All pts who have Injury of anatomical site, with 
morphology of Dislocation'

Please use labels and text to provide additional information.

'All pts who have Injury of anatomical site, with morphology of Inferior 
dislocation'

Widget behaviour appears to be that, if you double-click on an unexpanded node 
in the selection tree, then item actually selected is first list-
order descendent of node clicked on, if the tree were to be expanded. If tree 
already IS expanded, then item selected is same as that double-clicked on.
