Chrisahn added a comment to T364245: Recentchanges and cu_changes tables are occasionally missing revisions on multiple wikis.

This seems to have happened on dewiki. An edit doesn't show up on anybody's watchlist. https://de.wikipedia.org/wiki/Wikipedia_Diskussion:Beitragszahlen#Beobachtungsliste

Chrisahn added a comment to T262093: MoveLeadParagraphTransformInfobox should be rewritten to be more similar to mobile apps (allow more flexibility in lead paragraph identification).

Chrisahn added a comment to T263306: MobileFrontend displays second paragraph as first paragraph on dewiki (Moving article lead is broken).

Great! Thanks a lot, @Esanders.

Sounds good. When is this going to be live on dewiki? I'd like to have a look at some of the pages I listed above. Will I have to purge the pages after the fix is deployed?

A similar problem on ruwiki was fixed in 2018: T188825

Details:

  • The current heuristic for finding the first non-empty paragraph (and moving it to the top if necessary) works fine for >90% of all pages (e.g. most random pages), but sometimes fails:
    • Sometimes it moves the second paragraph to the top, not the first, and thus swaps the paragraphs. This is quite confusing for readers.
    • Sometimes it leaves the Infobox at the top and moves no paragraph to the top. This is inconvenient for readers.
  • It looks like these problems often (but not always) occur when the wikitext contains an image or an infobox before the first paragraph.
  • I couldn't find any articles with these problems in other Wikipedias than dewiki (but I only looked at about ten articles in non-de wikis).
  • The problem is present in the HTML delivered by the server, so it's not a CSS or JavaScript problem.
