Huh seems legit, I'm using boost and only up to the dash is highlighted, and the link doesn't work.

Yeah, I saw that thread, and can confirm the link doesn't work.

I sympathize with this bug as I wrote a big chunk of the code that does markdown to html conversion for piefed. I feel like every week or so some new edge-case pops up and I need to adjust my regex again. These community links are not standard markdown, so every app basically has to write their own bespoke solution.
