When you visit a page on SO other than the homepage (like 'Questions' or 'Unanswered' for example) there is some preview text shown below each question. (looks like the first X number of characters / words from the post body is displayed).
If a user includes some markdown formatting in the beginning of their question, how does SO avoid showing this in the question preview? For example if I were to type a link or an embedded code block, You don't see the markdown syntax
[link](link) in the preview.
