@texnixe The current thread is about the built in tags, but for me it happened with the code in this post, which also uses Html::figure.
I think because the snippet code has enough leading spaces on some lines to trigger markdown pre. It doesn’t happen with the final snippet at the end of the thread. I will post an issue if i can reliably replicate it again. I guess it could be a problem with Html::figure since thats the common element here.
