Let's say I have a page of products, having 2 attributes - size and color.
There are products of size 1 and 2, colors - black and white.
I choose white and products get filtered fine, however
if there are no products which are both "white" and "size 1",
"size 1" should disappear from the list of available filtering options,
however this doesn't happen.
Was this behaviour intended and can there be a solution - matching not only the products list, but also other attributes list against the selected filtering rules?
