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

• At English Wikisource, use "What links here (all NS)" and utilise "John Brown" for the target
• Go to "Disambig" tab and use "John Brown" as the link to disambiguate and hit load links

What happens?:

• The load displays two main ns links and none of the author ns: pages

What should have happened instead?:

• All pages listed on the disambig page should be loaded irrespective of namespace, or namespace of which one is in

Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc:

• ver. 6.2.1.0

This is important requirement, as Wikidata requires that each site have only one disambiguation page per term, so we need the load to be all namespaces, not solely the namespace of the existing page
