Invisible pedal lines not showing at all

In 3.4.1.9660 and also Feb 3 nightly:

I'm noticing that if a score contains pedal lines and all of them are marked invisible, then they aren't drawn at all - not even in the grayed out state. Adding a visible pedal line causes invisible ones to show up, but only on the same system as the visible one. Example - try adding a pedal marking to it: Invisible pedal lines.mscz

Apologies if a duplicate report.
