[css-pseudo] [css-fonts-4] Do properties added in CSS Fonts 4 apply to the `::first-*` pseudo-elements?

[yarusome]

Currently CSS Pseudo-Elements Module specifies for ::fist-letter and ::fisrt-line that:

The following properties apply to ::first-letter, ::first-letter::prefix, and ::first-letter::postfix pseudo-elements:

• all font properties (see [CSS-FONTS-3]) […]

and:

The following CSS properties apply to a ::first-line pseudo-element:

• all font properties (see [CSS-FONTS-3]) […]

This phrasing exludes properties added in CSS Fonts Level 4, e.g. font-palette and font-variant-emoji, from being applied to ::fist-letter and ::fist-line. Is this really intended?

Also, there's no WPT for this:

I think they should apply

Is this really intended?

No, that was likely just the latest reference at the time that part of the spec was written (same for CSS Color 3). Also, the references to defining specs are just parenthetical "see also" pointers and are listed under Informative References.

@yarusome do the explanations here plus the spec edit address your concern? WPT are still to be created, so not closing this yet.

[yarusome]

@svgeesus Yes, they do. Thanks for the updates!
