Possible bug (or at least not working the way I think it should).

1) Grid open in main view, left pane

2) Same grid open as View Pane on the right

3) Drag top level item (no parent) to subitem status under a parent in the right pane.

4) As item is added to the right (target) pane, the parent expands in the left (source) pane.  

Pane views should remain independent.  Taking an action in the right pane shouldn't cause the left pane view to change.
