In clojurescript mode and `c.ljc files , some namespaces are parsed twice

[viebel]

Hi,

When clojurescript mode is one and cljc files are shared, some namespaces are rendered twice: once for clojure and one for clj.

For instance, in this repo https://github.com/viebel/hickory, the parser namespace documentation contains twice the variables of parser namepsace.
