Reviewed by Tim Nguyen.

Align with the standard and other browsers. In particular

  https://drafts.csswg.org/css-color-4/#quirky-color
  https://drafts.csswg.org/css-values-4/#deprecated-quirky-length

mandate this and those are the only quirks applying to CSS.supports().
As stated there this is not applicable to @supports.
