Dropped "(" when following "]. " of citation

[reagle]

For some reason related to the CSL processing of chicago-fullnote-bibliography.csl, when an open parenthesis follows the closing bracket of a citation and a period, it is lost in HTML output.
In the example below, the "(" before "We" is missing in the HTML.
If I remove the period, the missing parenthesis will return.

It is being removed by mvPunct in l. 109 of T.P.Citeproc.

I think this traces to an issue in citeproc, dropTextWhile.
