On recipes that don't have input items, fixed_quality on assemblers will make the recipe draw quality overlays, despite outputting at normal quality.
I would honestly rather this be fixed by outputting the product at the correct quality (no other ways to output items at a certain quality), but that is likely closer to a feature request than a bug report.
The bare minimum mod needed to test this, if needed.
