I am not surprised at that behaviour, knowing that MI deals very badly with
non geographic objects such as ellipses and rectangles. It is easy to find
that if you convert the ellipse to a region, you will get the right results.
What is less understable to me is that one would get the right result with a
rectangle.
I have come to avoid using geometric shapes (rectangle, rounded rec,
ellipse, arc) as part of a map, by converting them to regions or polylines
as soon as created.
More like a workaround than a real solution.
