Reading comment should not throw exception

I have notice a discrepancy in how comments are read between cljs.tools.reader/read-string and cljs.reader/read-string.

In cljs.reader, as shown here no exception is thrown but nil is returned, concretely ignoring the comment.

Conversely, the following throws:

(r/read-string {:read-cond :allow :features #{:cljs ;; comment) ;;+> EOF

In my opinion the cljs.reader is the correct one and cljs.tools.reader should be patched, but of course there might be a reason I ignore to throw an exception.
