Pressing the Home and End keys selects the first/last items even if they are collapsed/hidden.

The DropDownContentTemplate is not applied to items in the dropdown menu that are dynamically added. 

The RadTabItem elements are not correctly displayed with long values set to the Header property when the TabOrientation="Vertical" and the used theme is Office2019.

Currently, if you have multiple tabs and the scrolling in the tabstirp area gets enabled, you can scroll using the mouse wheel. However, there is no behavior that handles the swipe gesture on touch devices (which is the alternative to the mouse wheel action). 
Add swipe scrolling support.

DECLINED: This issue is not reproducible with R2 SP1 2016 Release.

A System.Windows.Documents.Hyperlink' is not a Visual or Visual3D Exception is thrown when you click on a Hyperlink inside a RadTabControl and then try to scroll using the MouseWheel

When pressing the Alt key, the access key of a given element must be displayed. Inside the Header of a TabItem it is not. The issue is not reproducible with the standard MS TabItem. It seems that it is related to the Foreground binding of the control. There is a workaround as shown below.

<telerik:RadTabControl>
    <telerik:RadTabItem >
        <telerik:RadTabItem.Header>
            
                <AccessText Text="_Tab 1"
                            Foreground="{Binding RelativeSource={RelativeSource AncestorType=telerik:RadTabItem},
                            Path=Foreground}"/>
        </telerik:RadTabItem.Header>
    </telerik:RadTabItem>
</telerik:RadTabControl>

error appears when the control is placed inside a RadTabItem

The fix for this issue will be available with LIB (version 2019.1.204) scheduled for publishing on Monday, 4th February 2019.

A design time error occurs when referencing NoXaml assemblies. 

In R2 2019 there is a regression bug in RadTabControl.

The Align property is not respected in the following themes: Windows8Touch, Office2019

When there are tabs present which have their Visibility property set to Collapsed and the ScrollMode of the control is Item, scrolling the items via the arrow buttons skips items unexpectedly.
