Chrome landed a fix that supports this behind an experimental flag. It also added the following cases to the WPT tests to clarify certain behaviors: * Preserve empty items, with a whitespace after each comma: - `:is(,,,)` -> `:is(, , , )` * Trim trailing whitespace from an invalid selector: - `:is(::before:HOVER )` -> `:is(::before:HOVER)` * Serialize an invalid complex/compound selector as-is, even when the selector is valid outside of a forgiving selector list: - `:host(:is(.a, .b+.c, .d))`: unchanged after serialization. (No whitespace is added around the `+` combinator, since complex selectors are invalid inside `:host()`). - `:is(::before:HOVER, .a)`: unchanged after serialization. (`:HOVER` is not lowercased, since the compound `::before:HOVER` is invalid. `::before` is not allowed inside `:is()`) - `:has(:is(:has(.a+.b)))`: unchanged after serialization. (Nested `:has()` is invalid) -- GitHub Notification of comment by byung-woo Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/8356#issuecomment-5125703778 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
