Background size cover plus background attachment fixed not working in pages with scrolling in IE11

Question

I've always been using the following piece of code to make a background fixed as well as covering 100% of the page despite its size:

background-image: url('./background.jpg'); 
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-repeat: no-repeat; 
background-position: center top;
background-attachment: fixed;
background-size: cover;

Did anything change with IE11? Is there any way to make it work as before IE11?

Thanks to everyone for your comments! I found a way that actually Works in IE11. Placing the background as an image in an individual div with these properties: code height: auto; left: 0; min-height: 100%; min-width: 1024px; position: fixed; top: 0; width: 100%; z-index:-1; Check it here: nekutranslations.es/sf2
