title: HTML in Jenkins job descriptions
body: <p>I have two Jenkins instances running. An old (legacy) one at version 1.614 and a new one with 1.633.</p>
  
  <p>In the old one it is possible to use HTML in the job description (it even does syntax highlighting editing it). The new one doesn't. HTML content is escaped and shown as plain text. I could not find a change in the release notes explaining this behavior. Is there a configuration that I'm missing?</p>
