When using a diagram in the theme Windows8, the all the text in the RadComboBox controls inside SettingsPaneTextControl is not showing.

Please see the attached file for example.

In a newly created empty Silverlight project, the Theme is set to Windows 8:

StyleManager.ApplicationTheme = new Windows8Theme();

Create a RadDiagram in a xaml file

<telerik:RadDiagram x:Name="diagram">
            <telerik:RadDiagramTextShape Content="Test" />
            <primitives:ItemInformationAdorner.AdditionalContent>
                <telerik:SettingsPane Diagram="{Binding ElementName=diagram}" />
            </primitives:ItemInformationAdorner.AdditionalContent>
        </telerik:RadDiagram>

And the text in the RadComboBox controls inside SettingsPaneTextControl is not visible.

most other themes work fine, but Window8 is not.

I already updated to the latest Telerik Silverlight libraries.
