Re: [csswg-drafts] unicode-range and falling off the end of the font-family list (#7449)

> The relevant section of the spec is this: https://drafts.csswg.org/css-fonts-4/#cluster-matching

Is this section really relevant to this example? The steps quoted are to be used "[f]or a given cluster containing a base character, b and a sequence of combining characters c1, c2…", and are focused on the question of whether the entire cluster can be rendered from a single font; but here your example is about a single [base] character, not a cluster.

Hence, I think rule 7 of [§5.2](https://drafts.csswg.org/css-fonts-4/#font-style-matching) would have applied, which calls for "the user agent [to perform] a[n] **installed font fallback** procedure". While exactly how that works is explicitly left up to the UA, it seems obvious that it is intended to *exclude* web fonts and instead rely on whatever "installed fonts" are available.
