Comments, via reblogging, that I don't feel justify a full post on my real tumblelog.

This is a test

Tumblr appears to be stripping my Markdown headings of their HTML tags in the Dashboard. Why? I don’t know.

It always has. The Dashboard only allows a subset of tags to maintain security and consistent appearance. Currently it’s:

a, b, em, br, br, p, strong, i, ul, ol, li, 
blockquote, del, strike, code, pre, sub, sup

Tags are occasionally added to the list and styled appropriately in the Dashboard. Maybe the H-tags should be there.
