1860661 - [css-color] `none` values should be used as 0 during conversion.

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect)

Description

[Tiaan Louw [:tlouw]]

Currently in this wpt test:

https://searchfox.org/mozilla-central/rev/e4afef5d3ff67781dc1377912344694f3cf3a226/testing/web-platform/tests/css/css-color/parsing/color-computed-color-mix-function.html

there is an assertion that color-mix(in hsl, hsl(none none none), hsl(none none none)) serialized to color(srgb none none none), which is incorrect.

During conversion the none values should be dealt with as 0's, so the resulting serialization should be color(srgb 0 0 0)

This fixes a test where serializing none values should be treated as
0 for hsl and hwb.
