The issue
For some reason my YML code loses indentation after being posted.
I tried disabling BBcode and Rich Text extensions, edit and save the message again but still it loses indentation.
To me seems a "render" issue since if you press on the edited button (provided by flarum-diff extension, which I also tried disabling without success) it somehow reverts the text back to the correct indented text, probably it's forcing some sort of re-generation of the post HTML.
