This isn’t a bug, I added rules to make sure this does not conflict with Markdown’s ATX-style headers.

#This is a h1 header
# This is also a h1 header

In commonmark the space is required so I think you can safely ignore that.

Until we port over to commonmark, the headers are going to conflict with the autocomplete which doesn’t look good to me UX wise. :philosoraptor:
