All the e.g., <h4> tags generated by converting jupyter markdown to HTML are apparently assigned IDs with the exact text of the heading tag. For example:

### Let's go fly a kite!

Yields something like:

<h4 id="Let's go fly a kite!">Let's go fly a kite!</h4>
<a href="#Let's go fly a kite!">&nbsp</a>

Weasyprint doesn't like quotes in links:

Kozea/WeasyPrint#774

Notebook service has weasyprint==44. Upgrading to 47 seemed to fix the problem. We should push an update to onecodex==0.5.0 anyway and can do both at once.

Huh, that's bizarre. OK. Let's push an update to the notebook image tomorrow @polyatail.
