Store 6.0.2 cats in sales/discounts issue

Store 6.0.2

Issue: Categories don’t show in Sales & Discounts unless at least 1 channel has a Store field selected in “Edit Channel > Fields”.

Specifically: If site-wide in Channel settings your Store fields are all in “Edit Channel > Field groups”, with none selected individually in “Edit Channel > Fields”, then the Sales & Discounts don’t show any categories for Match Categories.

Suggested cause: /store/src/Service/ProductsService.php The function get_categories() get’s no results in the sql query if all channels only have Store fields in channel field groups.
