Markup in workitem description

Hi all,

I just edited a work item and added some HTML markup in the description. I used <b> and <pre> tags.

When I clicked "preview", my markup was rendered as expected: I saw bold and pre-formatted text. But after clicking save, the HTML tags are displayed verbatim in the work item description...

What is the correct way to preview and save markup in a workitem?

I'm using the web UI on RTC 2.0 I20090618-1753 with Firefox 3.5.
