https://fr.wikipedia.org/w/index.php?title=Fronti%C3%A8re_entre_l%27Inde_et_le_Pakistan&oldid=159781368#/map/0, at the bottom of the map view, is shown CSS rules to the user where would be excepted map title. I don't know if it's because of a bad syntax in wikicode, but I think that it shouldn't produce that result even in that case. I can't reproduce this on other pages.

@Framawiki: Well, is only that one single image affected, or many files? Just because I can also reproduce it does not necessarily mean that it's high priority, otherwise every issue that two people see would suddenly be high priority. :)
The displayed CSS seems to come from https://fr.wikipedia.org/wiki/Modèle:Légende/styles.css
However when I go to https://fr.wikipedia.org/w/index.php?title=Fronti%C3%A8re_entre_l%27Inde_et_le_Pakistan&debug=true&oldid=159781368#/map/0 , I get no map displayed at all. I wonder if that is related. Or not. My browser's Developer Tools show
