FYI, page previews currently runs on anything that's been identified as content in mw:Manual:$wgContentNamespaces. Would it be useful to add this namespace to the list of namespaces that are content ? Jdlrobson (talk) 04:25, 31 January 2022 (UTC)[reply]

I can help make this happen. Could you follow the guidelines on https://wikitech.wikimedia.org/wiki/Wikimedia_site_requests and discuss it on your wiki?

Note enabling page previews on this namespace would also lead this namespace to show up on different pages https://m.mediawiki.org/wiki/Manual:$wgContentNamespaces#Details so I want to make sure this was properly discussed. Jdlrobson (talk) 21:28, 31 January 2022 (UTC)[reply]

Something else seems wrong to me, as Anexo IS a content namespace. The console of mw.config.get().wgContentNamespaces reports [104, 0] and there is https://phabricator.wikimedia.org/T41866. So this seems like a Popups bug in that case. I will open a ticket. —TheDJ (talk • contribs) 16:56, 7 February 2022 (UTC)[reply]
