[Product] When hiding/removing the quantity selector block, variant switch is broken

[ludoboludo]

Describe the current behavior

If you hide the quantity selector block on the main product page or feat. prod section, the variant switch won't happen and error out because it's not able to run some logic as it's assuming that it should find a quantity selector input. p

Describe the expected behavior

Whether it's hidden or not, the form should work and let you add to cart.
