DockManager RestoreLayout operates incorrectly

Good Day,

I'm having a problem restoring the layout of the DockManager Panels (Please note that I'm also using the Document Manager). I have attached a sample project I've used to replicate my problem.

Steps to Reproduce:

Step 1:

Start Attached Application and click on Open Window 1 Button and Open Window 2 Button

Step 2:

Drag Dock Panel(Window 2) over Dock Panel(Window 1) and dock as Tab, close the application which will save the DockManager Layout to an XML file.

Step 3:

Start Application and notice the 2 Panels docked together perfectly as they were before we closed the application. Now undock Panel (Window 2) by double clicking on the Tab Name. Once Window 2 has been undocked from Window 1, re-dock Window 2 as before (See Step 2). And then close the application.

Step 4:

Start the application and you will notice the panels are not in the correct place.

Actual Results:

Window 1 and Window 2 are not in the same saved position when restoring the DockManager Layout.

Expected Results:

Panels to be in the same saved position after restoring the layout
