I've been considering opening an issue at Busy's GitHub. Or maybe I could report the problem through Utopian? I've read that Utopian is really strict and has very high standards, and I still haven't managed to gather the courage to try it out yet :P . Before reporting the problem to Busy, maybe I should try to find the fix for it too.
While we are at it, where is Busy's upvote button? Is it below the post? From the HTML I looked at, I noticed some things that seem to be icons and thought the upvote button might be in there, but I'm not sure. Is there a downvote button too? I couldn't find it. And Busy seems to have a feature to bookmark posts (at least it has a bookmarks section in the menu), but I still couldn't find an option to bookmark posts anywhere. I wonder if this is also hidden behind an icon.
