List of steps to reproduce (step by step, including full links if applicable):

• Go to https://no.wikipedia.org/wiki/Spesial:Innholdsoversettelse and observe the articles it suggests for translation.

What happens?:

• Many/most of the top suggestions already have articles in Norwegian Bokmål
• Some examples from just now: World War I, Joseph Stalin, Elizabeth I, Georgia (country)

What should have happened instead?:

• It should not suggest articles that already exist in the Norwegian Bokmål Wikipedia.

Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc.: MediaWiki 1.39.0-wmf.7 (800f261), ContentTranslation 670863b

This is most likely yet another iteration of our no/nb problems. The Norwegian Bokmål Wikipedia is located at https://no.wikipedia.org/ and has the database name nowiki, but its language code is (correctly) set to nb. So what I guess CX is doing is to check whether an article exists in nbwiki on Wikidata, while in fact it should check whether the article exists in nowiki.
