Timeline: All groups are disappearing when expand/collapse a group while the ItemsSource collection is updated

If you click on the collapse/expand button of a group (when the data is grouped) while you add or remove an item from the ItemsSource of RadTimeline, all items disappear.

To work this around set the AnimationManager.AnimationSelector attached property on all TimelineItemGroupControl elements to null. You can do this using an implicit style.

<Window.Resources>
    <Style TargetType="telerik:TimelineItemGroupControl">
        <Setter Property="telerik:AnimationManager.AnimationSelector" Value="{x:Null}" />
    </Style>
</Window.Resources>
