SCSS: Wrong property highlighting

[phts]

• variables are not highlighted

background-color: $color-body-bg;

• Ordinary values are not highlighted

position: absolute;
-webkit-text-size-adjust: none;

• value grayscale is partially highlighed

-moz-osx-font-smoothing: grayscale;

• value antialiased is highlighted

-webkit-font-smoothing: antialiased;

PS. Tested on built-in scheme e.g. Monokay. Naomi scheme is little better but still not good.
