In the SimpleSample demo,I drag TestControl into designsurface and then call UnloadDesigner but the destructors of TestControl never invoke

Puh..

At first it's correct behavior, because if you Undo, Instance is reused...

But, if you do 

        desItem.Services.GetService<UndoService>().Clear();
        GC.Collect();

it's also not called, so there seems to be an error. But atm. I've no time to search for it. If you find samt, I will fix.
