If a NDockingToolbar is set to:
- CanDock: true
- CanDockTop: true

The user can change per Drag&Drop the order and positions of the various toolbars showing up. Unfortunately it is also possible to move a NDockingToolbar above the NMenuBar, which looks very unfamiliar to the user.

While it is possible to maybe react on this after the user has moved the toolbar, by altering the properties:
- PrefferedRowIndex
- RowIndex

It should be possible to prevent this while the user is moving the toolbar. So exists their any way to make the NMenuBar sticky to the top while a NDockingToolbar is moved around?
