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

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

This only happens whenever the Panes are docked one above another in the DocumentHost.

Currently TabStripPlacement property is not stored on a RadPaneGroup as part of the xml when calling SaveLayout. The result is when this has been set to say "top", loading the same layout then causes all docked panes in the group to switch tab placement to the default of bottom - which is not the same as it was.

Changing the pane's state using context menu from floating to tabbed items leads to memory leak in MVVM scenario.

Available in LIB version 2016.2.530, it will be also available in the 2016 R2 SP1.

After certain expand/collapse of RadExpander that is placed inside a floating RadPane the DataContext of the RadExpander is lost

If the mouse is above an AutoHideArea while the theme of the control is changing an NullReferenceException is thrown.

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>

The Docking control must be placed inside DataTemplate.

Also it is possible to reproduce this behavior by executing this process:
  - Load a previously saved layout into the RadDocking control (note that the PanesSource is not set)
  - Set a PanesSource collection. Here the PanesSource objects are correctly added to the control but the previous items from the loaded Layout are not removed.
