Steps to replicate the issue (include links if applicable):
- On the English Wikipedia, Template:Documentation subpage is included in MediaWiki:Scribunto-doc-page-header.
- Go to any module documentation page that doesn't transclude the template directly and doesn't have a category link to Category:Module documentation pages. An example is this old revision of Module:WP/doc.
What happens?:
The page is not included in Category:Module documentation pages
What should have happened instead?:
Since Template:Documentation subpage is transcluded to the page, its categorisation should also work. The page should be added to Category:Module documentation pages.
Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
