-----------
Support resolving "none" values to non-calc/explicit symbols in relative
color syntax expressions
https://bugs.webkit.org/show_bug.cgi?id=324903
Reviewed by Darin Adler.
When resolving non-calc explicit symbols usage in a relative color expression
we now preserve none values from the origin color.
"The component keywords return a <number>, or none"
- https://drafts.csswg.org/css-color-5/#relative-syntax
A few test cases in the WPT test
css/css-color/parsing/color-computed-relative-color.html
that previously passed now fail due to still testing the old conversion to 0
behavior.
Updating those tests will be done in a separate change.
