Monochrome Section Display Bug

Seems the Monochrome display mode gets confused when a clipped object has a Hatch Pattern AND a Hatch Background?

IMAGES 1 & 2 - Viewport Capture in Layout space. Section: Black hatch with Red Background

IMAGE 2 - Clicked into SEC_A_00 Detail, which shows how it should actually look.

And for reference, here’s a thread for (I think) the same issues in the Mac Version
