Re: [csswg-drafts] [css‑fonts‑4] Create keywords for `unicode‑range` (#4573)

> If we exclude U+2764 from `unicode-range: emoji`, that means a font loaded using `unicode-range: emoji` will be unable to render <U+2764, U+FE0F> as a colored red heart, even though that would be an author's expected result, no? Or indeed if a bare U+2764 is used in conjunction with `font-variant: emoji`, I think an author would expect their "emoji" font to be used.

It sounds like we might need a little bit of an algorithm spec on top of the [RGI_Emoji_Qualification](https://unicode.org/reports/tr51/#def_rgi_emoji_qualification) property. Maybe it should say something about matching an RGI_Emoji_Qualification prefix of a longer [emoji sequence](https://unicode.org/reports/tr51/#def_emoji_sequence) (validity regex), and consider emoji variation selectors following the prefix even if they don't continue another RGI_Emoji_Qualification sequence?
