The ribbon tab doesn't get selec if you click in the exact middle of the header of RadRibbonTab.

To work this around, extract the ControlTemplate of RadRibbonTab and move the Grid with x:Name="ContentPanel" before the Grid with x:Name="HeaderPanel".

The HeaderVisibility property of RadRibbonTab doesn't work when changed at runtime.

A workaround is to use Visibility property of RadRibbonTab, instead of HeaderVisibility

NullReferenceException is thrown on start up of the application, when the IsMinimized property of RadRibbonView is set to True initially. For example, if you set it in XAML.

To work this around, set the IsMinimized property in the Loaded event handler of RadRibbonView.

private void RadRibbonView_Loaded(object sender, System.Windows.RoutedEventArgs e)
{
	var ribbonView = (RadRibbonView)sender;
	ribbonView.IsMinimized = true;
}

Currently, the RadRibbonTab GetChildrenCore method creates automation peers only for the elements in its Items collection. There is no peer created for the element in the Header. Add support for this. 

This missing peer, leads to that the TextBlock in the Header of the ribbon tabs is not highlighted when using a UI inspecting tool (like Snoop and its Automation option or UISpy.exe).
