There are 2 bugs - probably related:

1. Hitting enter after inputing quantity on quick order list on a product that has 1 or zero variants redirects to /cart
2. I am able to add submit quantity that does not respect quantity limits (bug video)

I think the fix should include::

• Let's prevent being able to submit a quantity that doesn't respect quantity limits.
• Let's only suppress cart notification actions on quick order list when there are 2+ variants on a product. For products with zero or 1 variant, let's respect the cart notification behaviour selected in theme settings on quick order list (removed this requirement, see this comment.
• Hitting "Return/Enter" keyboard key when a product has zero or 1 variant should not bring you to /cart (unless that's your selected cart notification behaviour)

I am working with the cart team in this ticket.
My PR opened the discussion about how this could be fixed and cart team is taking from there.

Most likely, the fix will come from this PR
I will keep eyes close to it
