How to prevent filter show out of stock items?

v 2.0.1.1

Am i doing something wrong here?

Lets say i have t-shirts in different brands. If i add filter for the sizes S, M, L and XL customers can filter their size eg. Large.

BUT if one T-shirt is sold out at size Large, then i dont want that particular T-shirt to show up when filtering..

Is there a way to prevent filter from showing items that DONT have that size left in stock?
