IE does not recognize declarations with space around parenthesis.

I compress my sheet using perfectionist's compact mode, and just discovered that lines like next are ignored in IE11.

.foo { transform: translate( -50%, -50% ); }
.bar { margin-left: calc( 5vw + 20px ); }
.baz { box-shadow: 0 3px 10px rgba( 0, 0, 0, .2 ); }

I am not sure you intended to support or not to support last versions of IE, but I definitely would love it if you do. Thank you for this awesome tool.
