Math in pager contents not rendered

[embray]

When the pager is cleared/updated with HTML content from a mimebundle, if that HTML contains equations, MathJax should be run over the pager.

For example, I was able to hack around this by appending to end of the HTML portion of a mimebundle:

<script type="text/javascript">MathJax.Hub.Queue(["Typeset", MathJax.Hub, "pager-contents"])</script>

but this smells like a maintenance burden, when really the pager should probably support displaying math from the get-go. Unless I'm missing something...
