See line 228 and below of https://fr.wikipedia.org/w/index.php?title=Vienne_%28Autriche%29&curid=15839&diff=101387243&oldid=101365362 . 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 ."
That diff looks as if refs were generally considered dirty and selser was not used for them. This seems to be a Parsoid issue: http://parsoid-lb.eqiad.wikimedia.org/_rtselser/frwiki/Utilisateur%3AGWicke%2FTest
