Title bar (including the Contextual tab header) goes over the Window (MinMaxClose) Buttons
The title of the RadRibbonWindow can't be trimmed when resizing the window. Even the window's buttons are overlapped
When the ItemTemplateSelector property is used the class which inherits the DataTemplateSelector is never called.
The MinimizeButton of the RadRibbonView have mismatched states(When the ribbon is collapsed the arrow should be pointing Up, and when the ribbon is collapsed should be pointing Down) not the other way around
If a RibbonView with Backstage menu is hosted in a RibbonWindow and the window's MinWidth and MinHeight properties are applied, when the Backstage is opened the size restrictions are no longer respected.
