Simple Mesh sans Normals

With a 4point surface as an input into the "simple mesh" component; There are no Normals when using that mesh as an input into a C# or VB component.

If I use a "deconstruct mesh" component they are there. If I build the mesh in a "construct mesh" component with the same 4 points - the normals are there, but not with simple mesh. 

Workarounds aside, using simple mesh with any brep results in a no-normal mesh - which seems like a bug.
