Customer reported platform

Steps to reproduce
1) Open Modo.
2) Select File > Open and open the attached scene.
3) Select Viewports > Topology.
4) Select "Retopo" and rotate the camera to where the face is visible.
5) Select the Topology Toolbar on the left, then enable the "Topology Pen" tool.
6) Press "K" to reveal the tool properties. Select "Fill" From the Mode selection.
7) Press "O" to reveal the viewport preferences menu. Set "Show Vertices" to "Always" on the "Active Meshes" tab.
