On this topic, the title has been changed from "lol" to "Essais d'historique".
In the History tab, that change is not visible (6th entry from the page bottom):
| Status | Subtype | Assigned | Task | ||
|---|---|---|---|---|---|
| Invalid | None | T85563 StructuredDiscussions history page issues (tracking) | |||
| Resolved | None | T184991 [frwiki] Topic title change entries in board history don't include new topic title (msg redefined in MW NS) |
I'm not sure why this truncates at all (it's a rendered version, not a user input limitation). If there's some reason to, it's way too short (and other untruncated lines are longer).
The line is not truncated. A user has decided that the new topic title was redundant and decided to remove it by overriding the message on wiki: https://fr.wikipedia.org/wiki/MediaWiki:Flow-rev-message-edit-title
The actual message in the code is $1 {{GENDER:$2|a changé}} le titre du sujet « $5 » en « [$3 $4] ».
@Trizek-WMF Can you handle that on wiki?
Thanks @SBisson. I should have checked the local messages first.
