Tesselation in Part Studio vs. Assembly

I have an airfoil I am working on. As airfoils go, it has a thin shell and quite sublte curvature at places, so I set the tesselation to "very fine" in the part Studio. I have a sufficiently beefy Nvidia Quattro grapics card and it worked as expected:

Then I inserted the same airfoil into an assembly to design (and visualize) the details of the mold setup. The tesselation was poor there, so I set it to "use best available" from the item context menu in the tree. The little diamond showed up next to the tree item, but tesselation was still poor:

How come, and how to overcome?

    I found a workaround, even if I don't understand it. Instead of inserting it directly, I first derived the part into it's own part studio, then put it into my assembly. Now it tesselates fine. I have no clue why that is, though. Appears like a bug to me.
