SSO markers drawn despite magnitude limit

[Atque]

We are presented with the option "Draw markers for objects with magnitude brighter than this", followed by a user-configurable value. However, no matter what limit is set, all SSO's are shown. See the screenshot below, where only objects brighter than +15 should be drawn, yet much fainter SSO's are:

Wait, it works for asteroids but not comets!

This feature was introduced when I tried to see a few hundred thousand objects. Here I concentrated on non-cometary minor bodies. Maybe I forgot a test for this value when rendering comets, it shows the tiny ring mark of a minor body.
