Application crashes with nested drag source

[ShadowDancer]

Hello,
I have TreeView in which all leaves may contain listview of items. Looks like dragdrop library is doing something wrong, as after selecting all items in listview and I doubleclick it I am getting InvalidOperationException("Property SelectedItem was registered as readonly and cannot be modified without authroization key"). How I can get around this error?

in System.Windows.DependencyObject.SetupPropertyChange(DependencyProperty dp) in System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value) in GongSolutions.Wpf.DragDrop.Utilities.ItemsControlExtensions.SetSelectedItem(ItemsControl itemsControl, Object item) w D:\projects\git\gong-wpf-dragdrop\src\GongSolutions.WPF.DragDrop\Utilities\ItemsControlExtensions.cs:wiersz 292 in GongSolutions.Wpf.DragDrop.DragDrop.DragSource_PreviewMouseLeftButtonUp(Object sender, MouseButtonEventArgs e) w D:\projects\git\gong-wpf-dragdrop\src\GongSolutions.WPF.DragDrop\DragDrop.cs:wiersz 782 in System.Windows.Input.MouseButtonEventArgs.InvokeEventHandler(Delegate genericHandler, Object genericTarget) in System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler, Object target) in System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs)

@punker76 Thanks! Can I use current head without suprises instead of nuget package?
