HTML headings with line breaks -> no heading and inconsistency between preview and rendered post

Oh this is very related to:

Markdown preview and result differ

Took a quick look out of curiosity. It looks like an issue with the Nokogiri library. [image] From what uses Discourse here: Loofah.fragment uses Nokogiri’s HTML4 parser. This could be fixed using Loofah.html5_fragment as long as Nokogiri >= 1.14.0 and Loofah >= 2.21.0. Discourse already uses Nokogiri::HTML5.fragment; that would make sense. Note: Loofah 2.21.0 is not yet released; currently in RC1.

I am OK to wait a few more weeks for Loofah to release

Will shoot out a Tweet to Mike to mention this popped up.
