Hi Christopher Thibeault,
Thank you for your query.
We would like to inform you that the Ribbon Contextual Tab Group header visuals (such as the colored header area above the tabs) are currently supported only when using a RibbonWindow.
We understand this might be important for your application, and we’ll be updating our documentation to clarify this limitation in one of our upcoming releases.
Please let us know if you need any further assistance.
Regards,
Sekar Sivalingam
