Thread title pretty much says it all.
This is a bit annoying.
After a bit more experimentation, it comes and goes.
Seems like when the galley is forced to reformat (e.g. by ewtering some notes that change spacing) it reappears.
This bug was reported during our beta period and we fixed it, so if you’re still encountering it, please provide some reproducible steps. It’s certainly possible that there’s a remaining case that we need to address, and we’ll be happy to look into it if you can provide some steps.
