Has anyone else had an issue with StationaryMargins="Header" or ="HeaderAndFooter"  since upgrading to 8.3 ?? When I turn it on the header seems to render itself half way down the grid, and I cannot see any data.

 I have pasted a copy of the markup below. If I remove the StationaryMargins attribute from DisplayLayout, everything works fine.
