Re: [csswg-drafts] [css-color-4] [css-color-5] inconsistent mentions of powerless components in `white`. (#8609)

> But yes, I see your point: if one or both of the colors to be interpolated is already in the interpolation colorspace, it will have a powerless component not a missing component. The current text assumes that all colors are converted into the interpolation colorspace, and the part about classifying missing components doesn't quite capture that.

I _think_ I brought this issue up with @tabatkins a while ago, and the conclusion was that the text ([source](https://www.w3.org/TR/css-color-4/#interpolation))

> Interpolation between [<color>](https://www.w3.org/TR/css-color-4/#typedef-color) values occurs by first converting them to a given color space

was interpreted to mean that conversion _always_ happened for interpolation, even when it was to the same color space, and so powerless components became missing. Tab may have a better source for that than my memory.
