True Hidden line - Fill

I have noticed that cells or shapes that are filled do not show up filled in the "True Hidden Line" reference file presentation. Is there a setting I may have missed or is the as designed? Note: The filled cells shown on the graphic were put into Layout after the presentation was set for demonstration.
