Imported CAD Solid Hatch vanishes in Textures Visual Style when Transparency is >0%

[omb_tsargent]

I am using Revit 2024
I have a planting family with a CAD file inserted into it. 

When I place the planting family in my project it looks great. 
In a view with the Textures Visual Style applied it looks great too.
UNTIL I increase the transparency of the Planting category (or by object) above 0%. 
When I set Planting transparency to 40% the Solid Hatch for the trees vanishes completely. 
Same at 1%. 
I would expect the material applied to the Object Style to not vanish, but to display the Material's Graphic's Shading Color, but with a 50% transparency. 

• Adding an Image to the Appearance asset for the material applied to the hatches also doesn't solve the problem. 
• Modifying Object Styles doesn't solve the problem.
• Modifying Materials in Object styles doesn't solve the problem.
• The issue only exists in the Textures Visual Style.
• When I select the planting family, it only shows the linework, the fill doesn't get selected and turned solid blue.
• Changing from Planting family to Generic Model family doesn't solve the problem.

If I import the CAD file directly into the project, I can adjust transparency as I would normally expect.

Am I missing a step in setting up my planting family? Or is it a bug that Nested CAD in a family will stop displaying filled regions in the Textures Visual Style when any transparency is applied?

Care to share the family and CAD file, to help troubleshoot?  This is hard to diagnose without.

You stated, "Solid hatch disappears when transparency is applied." This implies that it's a 2D CAD hatch, i.e., transparency won't work in such a case.

What type of object is this CAD import? Is it a 2D hatch, a mesh, a surface, or a solid?

Attached are the CAD file and the family.

In CAD, it is a 2D Hatch. The hatch is a "Solid" hatch eg. continuous fill, no pattern. 
Importing just the CAD into a project permits transparency. 
Importing the family with the nested CAD does not permit transparency. 
This doesn't feel intended.
