Subbu says on IRC " it could be something in what ve returned, could be a bug with parsoid's mapping of wikitext ranges to HTML ranges .. we'll take a look and see if that can be reproduced."

As for the plain span tag added,
"that is because the wikitext has link-inside-a-link in the ref. .. <ref>[ .. [[..]].. ]</ref> and HTML doesn't support nested A-tags. So, Parsoid splits up that outer link which causes that dirtying and probably showed up as edited ."
