ID 383654 - Topology viewport style can become stuck/render incorrectly

Problem summary
Topology viewport style can become stuck/render incorrectly. Switching to other viewport styles will continue to render incorrectly. This can occur through the viewport selection button or through the viewport styles popover.

Customer reported version
modo.12.2v1

Customer reported platform
windows10

Steps to reproduce
1) Open Modo.
2) Select File > Open... and open the attached scene.
3) In the "model" viewport, select "default" in the viewport and choose "Topology" from the resulting popover.
4) Select the topology toolbar on the left.
5) Select the "Topology Pen" tool.
6) Click and place several verts from "mesh_01" (the sphere) on "mesh_02" (the cube).
7) Press "Q" to drop the Topology pen tool.
8) Hover the cursor over "mesh_02."
Result: the cube will be highlighted, and the back-faces of "mesh_01" will render in front of "mesh_02" despite being behind it. Switching to other viewport styles will retain the transparency inherited from the Topology style.

Workaround
Unknown.
