In this situation:
<body class="conservancy-blog">
...
<video>
it turned out that this CSS:
body.conservancy-blog video {}
Did not apply.
So, this adds a hack to force the issue.
I noticed after I updated to jessie that fonts displayed strangely in
some browsers. I still have strange fonts on our website with Chromium,
but this change seems to have helped iceweasel.
