On special pages like https://www.wikidata.org/wiki/Special:SpecialPages the top tab says "CollabPad" instead of "Special Page" like at https://en.wikipedia.org/wiki/Special:SpecialPages . https://www.wikidata.org/wiki/Special:SpecialPages?uselang=qqx returns the message https://www.wikidata.org/wiki/MediaWiki:Collabpad , but that should be nstab-special (https://www.wikidata.org/wiki/MediaWiki:Nstab-special) according to https://en.wikipedia.org/wiki/Special:SpecialPages?uselang=qqx .
Not sure what happened here, but doesn't seem correct
