Master Filter using StoreFront Filtering

Short description of the issue

Collection Filter - Master filter with multiple collections on the same page

Reproduction steps

Create a filter on a collection page that allows you to add another collection as a separate section and utilise a metafield.

Then make sure the filter contains all options, even product is part of that collection or not.

Additional info

  1. Only the storefront filter should be used because the tag filter will not work in my case due to a limitation.
  2. Make sure that, on filter selection, it will filter all collections within the same page.
