Re: [csswg-drafts] [css-fonts-5] Add glyph scaling override descriptor to @font-face (#6075)

That's right -- and the same applies to all the units etc that are based on font metrics (like `ch` and `ex`): they don't vary according to which font face actually ends up getting used, which could be different for each character within the element, they're defined in terms of the "first available font" or similar language.

So if the first available font [for the specific character on which the measurement is based] has a glyph scaling factor in effect, that contributes to the metric it reports. But whatever the metric is, it's consistent throughout the element regardless of the mix of actually-used faces.
