      In addition to their current coverage, the index filter tests should verify that:

      • When a query with a shape matching an index filter is executed, the index referenced by the filter is not used to answer the query if that index is currently hidden
      • If an alternative non-hidden index is available in the filter, it is used to answer the query. Otherwise, the planner outputs a COLLSCAN.
      • Un-hiding the index restores the index filter behaviour
      • It is legal to set an index filter on a hidden index, but the index will not actually be used until it is made visible
