Description sideshowbarker 2023-09-17 08:08:45 PDT

At https://html.spec.whatwg.org/multipage/semantics.html#standard-metadata-names:attr-meta-name-15 the HTML spec requires that:

> [if] existing meta elements have their name or content attributes changed, user agents must re-run the above algorithm

…where “above algorithm” is the algorithm at https://html.spec.whatwg.org/multipage/semantics.html#standard-metadata-names:page's-supported-color-schemes-2

However, WebKit currently doesn’t conform to that requirement, which causes two of the tests at https://wpt.fyi/results/html/semantics/document-metadata/the-meta-element/color-scheme/meta-color-scheme-attribute-changes.html to fail in Safari.
