Re: [csswg-drafts] [css-forms] What is motivating using the `lab` interpolation color space in the default style sheet (#13496)

Also the disabled button styles (in the [same section](https://drafts.csswg.org/css-forms-1/#stylesheet-button)) use `in srgb` instead of `in lab`:

```css
button:disabled,
select:disabled,
input[type="color"]:disabled,
input[type="button"]:disabled,
input[type="submit"]:disabled,
input[type="file"]:disabled::files-selector-button {
  color: color-mix(in srgb, currentColor 50%, transparent);
}
```

I suspect that this inconsistency is not intentional.
