    From Blink r148714 by <apavlov@chromium.org>:
    
    If not a percentage, "from", or "to" value is used in a key list, the rule is erroneous,
    and due to the absense of recovery, the parser skips the following, valid CSS rule.
    
    On a related note, keyframes, whose selectors contain invalid keys, should be discarded
    altogether, according to <http://www.w3.org/TR/css3-animations/#keyframes>
