Changing the theme at runtime causes any horizontal ScrollBar inside the content of a RadPane to be scrolled to its end

Available with the 2015 Q3 release.

Application theme:

StyleManager.ApplicationTheme = new CrystalTheme();

Docking theme:

<telerik:RadDocking Grid.Row="2" telerik:StyleManager.Theme="Office2016">
	<telerik:RadDocking.DocumentHost >
		<telerik:RadSplitContainer>
			<telerik:RadPaneGroup>
				<telerik:RadPane Header="Description">
					<TextBlock TextWrapping="Wrap" Text="On the Documents tab above press Ctrl + Mouse Left button to display the Popup Menu. You can use the same combination on every tab."/>
				</telerik:RadPane>
			</telerik:RadPaneGroup>
		</telerik:RadSplitContainer>
	</telerik:RadDocking.DocumentHost>
	<telerik:RadSplitContainer InitialPosition="DockedBottom">
		<telerik:RadPaneGroup>
			<telerik:RadPane Header="NonDraggable">
				<TextBlock TextWrapping="Wrap" Text="This pane cannot be dragged, because it has its property CanFloat set 'False'."/>
			</telerik:RadPane>
		</telerik:RadPaneGroup>
	</telerik:RadSplitContainer>
</telerik:RadDocking>

If the Background property of a RadPaneGroup is set in Windows8 and Office2013 themes it is disregarded

When a Pane is floated and added to a specific position in a PaneGroup saving the layout saves its position as last Pane in the group

Regions in panes content are not resolved when the pane is unpinned and collapsed. This happens only when you change the regions in runtime while the pane is unpinned and collapsed.

Panes that are autohidden are cut if resized too much - this is due to limitation in WPF that popups should not cover more than 75% of the screen.

The PaneHeader is shown and then immediately collapsed. 

Setting the PaneHeader to null can be used as a workaround if the project uses the default theme.

Removing item from the PanesSource collection causes NullReferenceException

When Saving and Loading a layout which has empty DocumentHost an ArgumentOutOfRangeException is thrown
