Bug 1996532 [wpt PR 55671] - Revert "[Fonts] Enable monochrome emoji rendering in forced colors mode", a=testonly
Automatic update from web-platform-tests
Revert "[Fonts] Enable monochrome emoji rendering in forced colors mode"
This reverts commit f1333a8acc364a000bfafbf0c86790307e112272.
Reason for revert: moving this behavior to computed value time as per spec
Original change's description:
> [Fonts] Enable monochrome emoji rendering in forced colors mode
>
> This change introduces support for rendering monochrome (text-style)
> emoji when forced colors mode is active.
>
> Key changes:
> - Add `is_forced_colors_mode_` flag to `FontDescription` and propagate
> it from `Document` to all font resolution paths, including canvas and
> OffscreenCanvas.
> - Modify fallback priority logic in `ApplyFontVariantEmojiOnFallbackPriority`
> to force `kText` priority for emoji when in forced colors mode and
> `font-variant-emoji` is set to normal or unicode.
> - Make forced colors mode part of the font cache key.
> - Gate the behavior under the new `EmojiMonochromeRendering` runtime
> flag.
>
> This also brings canvas rendering behavior in line with the forced
> colors mode, ensuring emoji are accessible and consistently styled.
>
> Spec - https://www.w3.org/TR/css-fonts-4/#font-variant-emoji-prop
> https://www.w3.org/TR/css-color-adjust-1/#forced-colors-properties
