[LDView][LDCad] Bug rendering 49098.dat

[LDView][LDCad] Bug rendering 49098.dat
Hi, I was creating instructions with LPub3D when I encountered this bug.

The torus subpart of https://www.ldraw.org/parts/official-par...rtid=49098 isn't rendered.

I investigate a bit and notice there's no consistency in this bug. Even here on LDraw.org.
Coming next are screenshots of this part as viewed by several softwares :

in the part tracker :
- this one is a 200% view of the PT's thumbnails (maybe generated with LDView ?)

- this one is from the PT's 3D viewer, part is complete, yay !

- in LDView, note that the tree info module shows the primitive and knows that the quads should be rendered (red highlight) :

- in MLCad (the old man knows how do deal with parts) :

- LDCad  (BFC is working here) :

- LPub3D 200% PLI display unsing LDView (since LDView doesn't render the part correctly, it's obvious this one isn't correct) :

- LPub3D with the native rendering engine (works fine) :

- Last but not least, I inlined the torus primitive and "ta-da !" :

LDView finaly rendered the file nicely.

I can't remember when, but it's a bypass I allready used this year and that we discussed here. I used (maybe badly) the search option of the forum and didn't find the thread.

EDIT : The problem still exists in LPub3D
