Deactivated prim is still drawn in Maya's Viewport 2.0

[cblanchette97]

Describe the bug

In a scene with a mayaUsdProxyShape, deactivating a prim from the session layer (prim.SetActive(False)) normally prunes it from the viewport. After the Maya scene has been through a File → Save As, this stops working: the prim is correctly reported as inactive on the stage, but Viewport 2.0 keeps drawing a "ghost" of its geometry.

Steps to reproduce

Open baseline.ma .
File → Save As… to a new file (e.g. baseline_overwrite.ma).
Run switch.py, which switches /root/CHA_Sphere_1 between the USD proxy and a referenced Maya rig:
switch_to_rig() references the rig and authors active = false on the prim via the session layer.
switch_to_usd() unloads the rig and authors active = true.
After switch_to_rig(), the USD proxy geometry is still drawn in Viewport 2.0, on top of the rig.

Expected behavior

After SetActive(False), the prim's geometry should stop being drawn in Viewport 2.0, the same as it does before the scene has been saved.
