scs_bearing_blocks preview looks correct, but render is not complete

[tpimh]

I am using OpenSCAD 2024.10.15.ai20955 (git 335ed8eb2), but this can also be reproduced with earlier versions.

In order to reproduce, add any scs_bearing_block to your project and comment out if ($preview) line.

For some reason, only the bearing is rendered, but not the other parts of the bearing block.

This is how preview (F5) looks:

This is how render (F6) looks:

I expect the two to look identical (like sbr_bearing_block does). Not sure why the rendering only works partially.
