A "Various Artists" with an URL was merged into our canonical Various Artists of the same name while keeping credits, resulting in the relationship credit (as Various Artists).

You get the same effect when setting a relationship with e.g. Kanye West as Kanye West. Which is different in behavior from artist credits everywhere else.

In such a case, the credit field should either be set to be empty, or it should not be displayed on the website if artist name and relationship credit match.
