I've narrowed the problem down to the "display_unavailable_attributes" setting in Prestashop. Can somebody enlighten me how this interacts with the allow_oosp setting in Prestashop?
The combination of settings "hide unavailable attributes" and some products are "available for order" doesn't seem to work as expected.
I've recorded a video of the situation in de Prestashop Demo environment: https://drive.google.com/file/d/1p1sPI1jc8WAojfTml7nubTg3ZFFf1iez/view?usp=sharing
