Re: [csswg-drafts] [css-fonts-5] font-size-adjust with missing metrics (#6384)

Indeed, no adjustment when missing glyphs / metrics is probably the correct thing to do. "Best guess" fallback values are not particularly likely to be close to what the font actually looks like, and will as easily be too big or too small. Some of the time, the adjustment would end up being in the right direction, but it would be just as likely to do the opposite of what you want.

For `ic`, `1em` is the correct size for the vast majority of CJK fonts, so it might still be tempting to synthesize the missing measurement to that value, but then again, if your font is missing a glyph for `水`, how likely is it that it actually is a CJK font?
