Windows 8 RadTreeListView does not show drag preview

[Stephen]

I am using Windows 8 theme with RadTreeListView version 2020.1.218.  I'm trying to get it to preview what is being dragged while dragging but that doesn't seem to be available.  My main code is more complicated but I also reproduced this with some really basic code:

        <telerik:RadTreeListView ItemsSource="{Binding Samples}" IsDragDropEnabled="True" IsDragPreviewEnabled="True">
            <telerik:RadTreeListView.DragCueItemTemplate>
                <DataTemplate>
                    <TextBlock Text="test"></TextBlock>
                </DataTemplate>
            </telerik:RadTreeListView.DragCueItemTemplate>
        </telerik:RadTreeListView>

The classes referenced are just simple example classes; the 'Samples' property is on the view model and is a collection of classes that have a single property.  I am referencing the NoXaml packages as well as the Windows8 theme package.  When I start this application it shows the grid correctly and lets me start a drag and drop, but there is no preview.  I have also tried this without the drag cue item template set with the same result.  

Am I missing something?  Is there not a way to do this with Windows 8 theme?

I've tested this, but it works properly on my machine. Can you please check the attached project and tell me if I am missing anything?
