I would like to look at this bug personally for help.
And if possible I would like to fix and make PR.

if I figure out the difference between 'editor preview' and 'render module'
Maybe that could be key to solving this problem.

So for that I little bit look at editor code github.com/Requarks/wiki@9ccd1f82e9/client/components/editor/editor-markdown.vue

And now I'm trying to find 'render module'
would you let me know what component rendering the page?

and any extra info would be help
