[csswg-drafts] [css-color-4] Should lab() colors which are outside the sRGB gamut be rendered on capable displays? (#4646)

smfr has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-color-4] Should lab() colors which are outside the sRGB gamut be rendered on capable displays? ==
Lab and LCH colors can be outside the sRGB gamut. https://www.w3.org/TR/css-color-4/#specifying-lab-lch says nothing about how to render those colors, other than not clamping lightness.

There is text about how to convert lab/lch to sRGB, so implementors may take this to mean that lab/lch should be converted to sRGB for rendering, but UAs that wish to support extended color rendering may choose to map lab/lch into some other working colorspace. I think the spec should make this clearer. Maybe issue 300 needs to be resolved before that happens.
