NemesisIII reports that when VEditing a page, existing reference numbers do not appear as "superscripted" as they should.
See section "projet" of https://commons.wikimedia.org/wiki/File:Bug_%C3%A9diteur_visuel_affichage_appels_de_r%C3%A9f%C3%A9rence.png (from https://fr.wikipedia.org/wiki/Avenue_Foch?veaction=edit ).
Number 3 and 4 are existing references, and they are very low. Number 5 instead is a newly added reference, which displays ok (note that this reference does not really exist in the article, it was added just to take the screenshot).

According to my tests, only fr.wp seems affected. I was able to reproduce this with
*Firefox (both Vector and Monobook)
*Chrome (Monobook)
*Opera (while logged out).

Version: unspecified
Severity: normal
