@SD1982 so actually the behavor you described is normal Because the product you selected is allowed to be ordered out of stock
I you try the same action with a Mug or example you'll see that the add button is disabled

I still created a PR to improve the check server side and use a more appropriate exception, but this issue can be closed anyway
