That installation uses `""base_url"": ""/collection-analysis/""`

Weirdly all of the other links on that page - to facet results, sort orders, row permalinks etc - work fine. It's JUST the `next_url` one that is broken.

Also broken in their JSON: https://ilsweb.cincinnatilibrary.org/collection-analysis/current_collection-3d4a4b7/bib.json?_size=1 returns
