<ol> does not look right in forum posts

Look how ordered lists look in posts. It does not look right and there should be some css problem.

1. one
2. two
3. three

Let's just test some <ul>s too:

• one
• two
• three

For reference, I see this happening in Firefox 3.6.3, Windows XP, and here is screen shot (from this question).
