mime-icon in plone/app/contenttypes/browser/templates/listing.pt fails to render icon with VirtualHostMonster

[Rudd-O]

Given a Plone site X.com inside a Plone instance, with a VirtualHostMonster configuration that roots https://x.com/ properly as per spec, the mime type icon listing URL ends up being:

                  <td>
                      <a href="https://rudd-o.com/intranet/government-backdoors.jpg/view" class="contenttype-file state-missing-value url" title="File">
                         <img class="mime-icon" src="/X.com/++resource++mimetype.icons/image.png" />
                      </a>
                      <a href="https://x.com/image.jpg/view" class="contenttype-file state-missing-value url" title="File">image.jpg</a>
                      
                    </td>

Note that the img should be rooted at /++resource++mimetype.icons/image.png without the /X.com added at the beginning.

This should be reproducible with vanilla Plone 5.2.3.
