Unpublish variant but still in front end product

Hello, when I unpublish a variant for one product, this variant still in front end of product variants
example: I have a tshirt whit size S-M-L-XL, if I in BO unpublish a size M, this size still available in FO
I test also in your demo site this features and bug still remain

Hi mariocasit,

When a variant is unpublished in the backend, we still can see it in the listing of variants in the frontend.
But it cannot be added to cart, a message 'No Stock' appears.

ok, thanks guys !
