When a product has: qty <1, and is set to "Backorders: Allow Qty Below 0..."
Is it also required that Stock Availability be set to In Stock before a customer can purchase this item?
Qty: 1, Backorders: Allow Qty Below 0, Stock Availability: Out of Stock
Can this product be purchased under default Magento behaviour? Or does it require stock availability to be set to "In Stock"?
Magento documentation is silent on this.
