[MonoDevelop] Stetic add-in and treeview widget event question

[Paddy Joy]

After playing around with this for a bit more I have found that when a 
user clicks on a treeview item the ButtonPressEvent is not fired however 
when releasing the mouse button the ButtonReleaseEvent is fired.

Is this a bug? Should the ButtonPressEvent be fired when the user clicks?
