FIXED: [2021.x] Active Instance Parameter disables line mat

When using a Line-MAT for an instanced line, setting the active-arguments in the instancing-page to anything (even though its valid otherwise), completly disabled the LineMATERIAL and it no longer gets rendered.

Thanks for the report.

I’m not able to reproduce this in the 2022.20000 series, so I think it’s been fixed.
