It seems that saving the layout to a file is the problem, I have modified your sample application to show this.
Replace the LayoutLazyLoading\MainWindow.xaml.cs file with the code below. Then just run the sample browser and run the Docking -> Lazy Loading sample. You just need to immediately close the Lazy Loading window and then open it again (you don't need to use any of the menu options). Do this repeatedly and you will see that the Toolbox tool window moves down the screen.
