Block Search Refinements
It's possible to include refinements for broad categories that are blocked for subcategories. If a customer navigates to the subcategory without selecting the blocked refinement, the blocked refinement isn't visible in the subcategory.
However, if a customer selects a refinement and then navigates to a subcategory where the refinement is blocked, the refinement is still shown, so that the customer can still relax the refinement.
