[Canapin (Coin-coin le Canapin)]

It was mentionned here, though the issue didn’t have a dedicated topic yet.

Category names don't wrap like tags , causing overflow on mobile

Long category names also overflow on the topic list. Because it’s very minor and slightly related, I’ll leave this here instead of creating a new topic (feel free to move it if necessary): [The image displays a forum page on a mobile device showing a list of event posts, with the highlighted event being "Calendrier CDC35 2024/25". (Captioned by AI)] Category names should ideally be short and it was the first time I saw this behavior.
