Re: [csswg-drafts] [css-fonts] Improve implementation guidance for font-kerning (#7958)

My mental model is that text is segmented into script runs, with "neutrals" adopting the script of their context. (Some hand-waving about behavior of neutrals at boundaries....) At the point where the font shaping engine performs kerning of a given piece of text, *some* decision must have been made regarding script, because it is an input to the shaping process. Then it's as simple as letting the `font-kerning:auto` value behave according to the resolved script of the text run being shaped.

So in your example, I'd expect the parentheses to be considered part of the Japanese text run, where no kerning is to be applied.
