It looks like the function controlling this behavior is
`org-export-format-source-code-or-example`, in org-exp.el:

                    (if (string-match "<pre\\([^>]*\\)>\n*" rtn)
                        (setq rtn
                              (concat
                               (if caption
                                   (concat
                                    "<div class=\"org-src-container\">"
                                    (format
                                     "<label
class=\"org-src-name\">%s</label>"
                                     caption))
                                 "")
                               (replace-match
                                (format "<pre class=\"src src-%s\">\n" lang)
                                t t rtn)
                               (if caption "</div>" "")))))

So the <pre> tag gets inserted first, then later gets replaced by <pre
class="src src-R"> ?
