DocumentWindow CloseButtons dissapear on layout restore

When saving the DockSiteLayout using the serialize, after restoring the layout, the DocumentWindows no longer have the Close Button on them. I tried changing the value of IsCloseButtonOnTab to true/false on the TabbedMdiHost which now has no effect.

I have the following simple code example to clearly show the problem.

run the sample and click on "Save layout", then "Restore Layout" - the close buttons on the tabs are now gone.

Many Thanks,
Sean.
