Syntax highlighting seems to be not working inside a list

Contribute Bug

  • My code from the first post works on CommonMark tester.
    It is correctly idented (but not highlighted because as I see CommonMark does not highlight code at all).
    So there is a clear difference: Discourse breaks my case №2 (3 back-ticks syntax) and CommonMark tester correctly renders it.

  • GitHub code from my post 3 does not work on CommonMark tester.
