Description Sam Weinig 2024-04-20 10:10:00 PDT 
Since implementation support for missing components there has been a change to the spec to require "analogous components" to be "carried forward". (see https://www.w3.org/TR/css-color-4/#interpolation-missing)

Essentially, if you are interpolating a hsl() color with a lch() color, in the oklch() color space, a missing hue value in in either the hsl() or lch() color should be respected.
