Q:

Autoprefixer not adding prefix for IE

I'm trying to use Grunt-Autoprefixer in my project but its not adding prefix for IE9 transform -ms-
http://caniuse.com/#search=transform
I have IE in my browserlist array Explorer >= 8
browsers: [
                "Android 2.3",
                "Android >= 4",
                "Chrome >= 20",
                "Firefox >= 24",
                "Explorer >= 8",
                "iOS >= 6",
                "Opera >= 12",
                "Safari >= 6"
            ]
yet, transform: whatever becomes
transform: whatever
 -webkit-transform: whatever
What am i missing?
