We have a question about an issue affecting the refining filter by size. Filter by size works with tags added to products, however the filter built in this way is unaware of the stock level of the items. So what happens is this:
in a listing you filter by (let's say) size S, the listing gets updated, then it may happen that you click on one of the products and when you land on the product page you find out that that size is not available.
Our question is whether there is a way to make filters aware of the inventory, so that what you see in the filtered results can actually be purchased because available in stock.
