Re: [csswg-drafts] [css-inline] `text-box-edge: ideographic` and `ideographic-ink` should use ideographic fonts in the cascade list (#10928)

> I'm a bit uneasy about this, as I'm worried that determining the "first available ideographic font" may be quite tricky in the general case -- issues like on-demand webfont loading and incremental font transfer may complicate things here.

I agree determining if a font is an ideographic font or not is very tricky, but for this specific case, it's not that tricky depends on #10850. The current spec requires the `BASE` table, so it should be straightforward to find the first font that has the specified tags in the `BASE` table.

If #10850 is going to synthesize these metrics from some glyphs, it's also feasible--the first font that has the glyphs.

If #10850 is going to some other methods, I don't know how else we can synthesize, but we can discuss.
