This is a bit less complicated than lengths because there's no cycle possible which could turn the color-scheme declaration invalid afaict. So it's just that we need to defer the colors when color-scheme is specified, which is slightly annoying, but maybe not too bad. I had to tweak a bit the code to defer properties to fix a bug that we were papering over accidentally. We were using the wrong registration here: https://searchfox.org/mozilla-central/rev/f60bb10a5fe6936f9e9f9e8a90d52c18a0ffd818/servo/components/style/custom_properties.rs#1613 That's the registration for reference.name, not for name, which papered over some issues. The fix is simple tho, which is storing a single CustomPropertiesMap. Differential Revision: https://phabricator.services.mozilla.com/D211860
