Oh apologies, still work in progress here. Is something missing?

Yes, tests are no passing because of the workaround I've done with _catalogs variable in Patient content type. Will open another PR (to be merged before this one) to make the product compatible with senaite/senaite.core#2662 and rely on registry instead of _catalogs attribute.

Ah ok, I actually missed the failing tests here.
Probably we should consider own Catalog Queue Processors per content type instead of this _catalogs attribute and drop the multiplexer completely

Since senaite/senaite.core#2662 , we rely on a setting in the registry (catalog_mappings). We still support _catalogs for backwards compatibility though.
