DXTabControl headers are not rendered correctly when the Header and Visibility properties are updated using data binding

I have a DXTabControl that is contained in a UserControl. The UserControl is hosted by a DocumentPanel in a DockLayoutManager.

The tab control is populated by a set of tab items, and the header and visibility of the tab items are updated using data binding:

XAML
<dx:DXTabControl.ItemContainerStyle>  
    <Style TargetType="{x:Type dx:DXTabItem}">  
        <Setter Property="Header" Value="{Binding Header}"/>  
        <Setter Property="Visibility" Value="{Binding Available, Converter={x:Static mvvm:BoolToVisibilityConverter.ToCollapsed}, Mode=OneWay}"/>  
    </Style>  
</dx:DXTabControl.ItemContainerStyle>  

The problem is that the Header text is not shown when setting the Visibility to "Visible" (see screenshot). (But the layout, i.e. size, seems to be correct.) If I select a tab, the header text will be shown correctly for that tab.

As a test I modified the registration of the Header property in HeaderedSelectorItemBase<TContainer, TItem>, by adding FrameworkPropertyMetadataOptions.AffectsRender as a property option:

C#
public static readonly DependencyProperty HeaderProperty =  
    HeaderedContentControl.HeaderProperty.AddOwner(typeof(HeaderedSelectorItemBase<TContainer, TItem>), new FrameworkPropertyMetadata(null,  
        FrameworkPropertyMetadataOptions.AffectsRender,  
        (d, e) => ((HeaderedSelectorItemBase<TContainer, TItem>)d).OnHeaderChanged(e.OldValue, e.NewValue)));  

After this change, the header text seems to be presented correctly. Is this something you can look into?

I have not had the time to create a repro, but if you need one I will try to find the time.
