I just checked dev docker image and unless the changes have to yet landed on nightly build its not fixed and its arguably worse.

In 0.3.12 pseudo-xml tags output from model is rendering just fine:

v0.3.12

In 0.3.13 tags were displayed w/ HTML escape sequences:

v0.3.13

In dev tags are not displayed at all because they are treated as actual HTML tags:

dev

I think 0.3.12 had correct bahaviour and now its broken even more.

Thank you. I can confirm that pseudo-xml tags now render correctly but it seems there's now an issue with markdown code block and mermaid diagram detection.

v0.3.12 renders everything correctly:

v0 3 12

dev displays raw markdown instead of rendering it:

dev
