FYI, I've heard a couple reports ^[1.1][1.2]^ that the spoiler tag isn't rendered properly on some front ends currently. Despite that, I haven't altered my usage of it, as I don't have any viable alternative at the moment.

  On my client, it's all expanded and I see all the formatting characters. It looks/works great in a browser though.
