Problem embedding Tableau Public map

Hi. We’re using your Origami theme for a project and trying to embed a
Tableau Public map into a Wordrpess post (self-hosted WordPress). If
you hit this link, you’ll see that the map loads for a second and then
disappears: http://www.nlgjaconnect.org/2014/?p=154

This is a direct link to the map:

I saw one other reference to this problem in your support section, but
there didn’t seem to be any resolution published publicly:

Tableau public Viz

Is there a fix or workaround for this?
