Scientific notation is not properly supported in keyframe selectors #332

@keyframes a {
    from {
        content: 'b';
    }
    to {
        content: 'c';
    }
    25% {
        content: 'd';
    }
    1.5E1% {
        content: 'e';
    }
    1E1% {
        content: 'f';
    }
}

The CSS spec about <percentage> allows any <number> before the %, which includes number in scientific notation. Both Firefox and Chromium parse the 1.5E1% and 1E1% properly, but this validator reports errors
