SelectedItem brush color problem

[Mark]

I'm using TwoWay binding on the SelectedItem property of the RadTreeListView control to sync my view and view model:  

SelectedItem="{Binding SelectedItem,Mode=TwoWay}" SelectionMode="Single"

It appears that the selected item brush color is not applied to the SelectedItem in this scenario:

Load control
Expand tree
Collapse tree
Set SelectedItem in view mode

In other scenarios, the selected item brush color is applied correctly.
