Event Timeline

Tacsipacsi changed the subtype of this task from "Task" to "Bug Report".Jan 21 2022, 9:54 PM
Tacsipacsi added a subscriber: Tacsipacsi.

The wikitext contains

{{ Template:Main Page/WM News
  | lang = <translate><!--T:15--> en</translate> | dir = {{dir|{{int:lang}}}}<!-- TO BE MIGRATED -->
}}

Probably the <translate> tags are not removed, and they cause issues in {{LangSwitch}}. Actually, this translation unit shouldn’t be there in the first place, the above code block should be replaced by {{Main Page/WM News|lang={{PAGELANGUAGE}}}} to avoid translators doing unnecessary work and breaking the output with the legacy parser as well.

T295834: Add special handling for annotation tags in template arguments is related and might solve this if @Tacsipacsi's analysis is correct (we haven't yet looked at this).
