[csswg-drafts] [css-color-4] Does CSS Color normatively require that HTML elements use/match system-colors in the UA stylesheet? (#7781)

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

== [css-color-4] Does CSS Color normatively require that HTML elements use/match system-colors in the UA stylesheet? ==
The WPT test [css/css-color/system-color-consistency.html](https://wpt.fyi/results/css/css-color/system-color-consistency.html) seems to require that the UA stylesheet use (or at least match at computed value time) the [system-colors](https://www.w3.org/TR/css-color-4/#css-system-colors) defined in CSS Color 4.

```
      test_computed_value('color', 'ButtonBorder', style.getPropertyValue('border-color'), 'resolves to the same color as the border-color of a ' + element.name);
```

I can't tell if this is a real requirement of the spec, or just something that the spec is suggesting. If it is a real requirement, it would be helpful if the spec was updated to explicitly specify which HTML elements and properties this applies to.
