The computed value for the root element is always 'auto' in WebKit. This causes a bunch of wpt failures in https://wpt.fyi/results/css/css-color-adjust/meta [1] https://drafts.csswg.org/css-color-adjust-1/#color-scheme-meta 1603800 1 webkit-bug-importer 2020-01-07 14:39:34 -0800 <rdar://problem/58388532> 1906021 2 ntim 2022-10-16 19:00:22 -0700 The tests are now at https://wpt.fyi/results/html/semantics/document-metadata/the-meta-element/color-scheme?label=master&label=experimental&aligned&view=subtest&q=color-scheme 1906047 3 rune.lillesveen 2022-10-17 01:04:27 -0700 The spec changed after I reported this issue. The meta element no longer sets presentation attributes. This is probably a Wontfix. 1977815 4 mike 2023-09-15 21:54:08 -0700 Resolving as Wontfix per https://bugs.webkit.org/show_bug.cgi?id=205798#c3. (There are still a couple failing tests in https://wpt.fyi/results/html/semantics/document-metadata/the-meta-element/color-scheme/meta-color-scheme-attribute-changes.html but those are unrelated to this issue — and the other failing tests in https://wpt.fyi/results/html/semantics/document-metadata/the-meta-element/color-scheme are fixed by https://github.com/WebKit/WebKit/pull/17817.)
