This change gives the font selection code access to the data from the @font-face rule that defined the font - and uses it to apply font-variation-settings inside @font-face rules.

Testing: We don't run wpt with layout_variable_fonts_enabled=true yet. I've attached a test case that is fixed by this PR.
Part of #37236

Sorry for the delay in reviewing. I really meant to get to this sooner. This looks good to me, apart from a few nit-picky things which I've outlined below. Great work!

I think we shouldn't add an intermediate type here and just keep these separate for clarity:

Suggested change
Stylesheet(
Box<FontFaceRuleInitiator>,
StylesheetWebFontLoadFinishedCallback,
),
Stylesheet {
stylesheet: DocumentStyleSheet,
font_face_rule: FontFaceRule,
callback: StylesheetWebFontLoadFinishedCallback,
},

That makes clippy unhappy because the two enum variants now have a great difference in size. We have to Box something. I'll try and make it a bit cleaner.

fonts: Compute applied variations depending on originating `@font-fac…
bd0254e 
…e` rule (#40647)

This change gives the font selection code access to the data from the
`@font-face` rule that defined the font - and uses it to apply
`font-variation-settings` inside `@font-face` rules.

Testing: We don't run wpt with `layout_variable_fonts_enabled=true` yet.
I've attached a test case that is fixed by this PR.
Part of #37236
