Azure CDN - Invalid characters when add content-types
<p>From the documentation:</p>

<blockquote>
  <p>The text field can contain a comma-separated list of content-types that should be enabled for compression via http Accept-Encoding/Content-Encoding.</p>
</blockquote>

<p>On the <a href="https://azure.microsoft.com/en-us/documentation/articles/cdn-troubleshoot-compression/#" rel="nofollow noreferrer">Troubleshoot</a> page - there is even screenshot with content-types added.</p>

<p>But when I'm trying to add new types (<code>image/jpeg</code>, <code>application/javascript</code>) - I have an error:</p>

<blockquote>
  <p>"Invalid characters. Characters allowed are alphanumeric, -, +, . and
  /."</p>
</blockquote>

<p>What I'm doing wrong here?</p>
