To reproduce the steps, load the sample web page from the _site directory and follow these steps:
- Increment the Quantity counter once or twice. It should have a number greater than 1.
- Click "Add to cart" and the Snipcart shopping cart will appear with the correct quantity.
- Close the shopping cart with the 'x' at the top right corner.
- Change the quantity to any new number besides 1.
- Click "Add to cart" again.
The second time the Snipcart shopping cart appears, the quantity specified by the data-item-quantity attribute of the "Add to cart" button is ignored and only a single new item is added to the cart.
