This is by design, and how Markdown works.. put it in a code block unless you want it to be interpreted as illegal non-whitelisted html.

> On forums that are pretty software intensive, i.e., people posting lots of code… the preformatted text ctrl+k thing doesn’t cut it. I’m constantly having to edit posts and do this technique: Is there an easy way to just change this button to be the CODE button and default it to whatever makes sense for your community? There is no amount of tutorials that can fix this problem… the problem is people look at the tools in front of them and the pick the one with CODE in it. Which turns …
