CCC doesn't hint the CSS values inside @media and @keyframes

[doxhung]

You can try the code below to test. CCC works properly when hinting the CSS properties (position, list-style...). But after we enter the colon right after a CSS property, the CCC doesn't show the value list of that property.
I hope you can fix this issue soon. Thanks much for your very useful plugin. It's very awesome.

@Keyframes sample
{
0% {position: relative;}
100% {list-style: none;}
}

@media screen
{
div.test {position: relative;}
}
