I'm seeing something I hadn't noticed before in src block html exports. Instead of producing structures like:

<pre>

<code>

<span>...</span>

<span>...</span>

<span>...</span>

</code>

</pre>

each individual like is wrapped in its own <code> tag.  In regular HTML exports this doesn't really affect display, but in exports to reveal using the highlight.js plugin, code display gets messed up.

From what I can tell these code tags are generated in org-html-do-format-code, in this section which starts on line 22459 of my pretty recent org:

(org-export-format-code
     code
     (lambda (loc line-num ref)
       (setq loc
    (concat
     ;; Add line number, if needed.
     (when num-start
(format "<span class=\"linenr\">%s</span>"
(format num-fmt line-num)))
     ;; Transcoded src line.
     (format "<code%s>%s</code>"
                      (if num-start
                          (format " data-ox-html-linenr=\"%s\"" line-num)
                        "")
                      loc)
     ;; Add label, if needed.
     (when (and ref retain-labels) (format " (%s)" ref))))
       ;; Mark transcoded line as an anchor, if needed.
       (if (not ref) loc
(format "<span id=\"coderef-%s\" class=\"coderef-off\">%s</span>"
ref loc)))
     num-start refs)

This code seems to have been around for a while so I don't know whether this is new behaviour, but I don't think I've seen line-level <code> tags before.  Can anyone confirm?

See also a MWE in this bug report, which is probably erroneously filed in the org-re-reveal repo:

I'd love to know whether this is expected behaviour, or if I've gone wrong somewhere!

THanks,

Matt
