ID 361768 - Static meshes do not properly occlude other mesh items when in the Topology layout.

Problem summary
Static meshes do not properly occlude other mesh items when in the Topology layout.

Customer reported version
modo.12.1v1

Customer reported platform
windows10

Steps to reproduce
1) Open Modo.
2) Open the attached scene.
3) Switch to the "Topology" layout.
4) Select the "Low_Poly" item.
Result: The wireframe of the Low Poly item is shaded differently when the "high_poly" mesh is occluding it.
5) Hide the "high_poly" mesh and reveal the "high_poly_static" item.
Result: The wireframe is shaded with no ghosting, and appears to be in front of the static mesh (which is identical to the non-static version).
