After clicking 'Citation,' we do not get a scrollbar if one is needed

E.g.

The problem lies in that Carto is using JScollPane, but the API documentation here doesn't match what appears to be happening. In particular, that API is not attached to anything in the jquery cache. It does look like our version of Carto is still using JScrollPane (at least to judge by "jspScrollable" being attached as a class to the scroll pane), but I don't see a way to add or reinitialize it for small infowindows.
