hasCombinedRelationManagerTabsWithContent bug

I think there's a bug when using this method :

 public function hasCombinedRelationManagerTabsWithContent(): bool
    {
        return true;
    }

 public function hasCombinedRelationManagerTabsWithContent(): bool
    {
        return true;
    }

Error :
