Created attachment 460411 [details] Reproduction Example The `@supports selector ()` fails for shadow DOM pseudo element tests. An example for supported shadow DOM pseudo element styling is `input::placeholder { color: orchid }`. Therefore the expected behaviour would be that `@supports selector(input::placeholder) {` matches. Furthermore the expected behaviour would also be that `@supports not selector(input::placeholder) {` does NOT match. Instead the current behaviour is that `@supports selector(input::placeholder) {` does NOT match. In addition the current behaviour is also that `@supports not selector(input::placeholder) {` does match. This behaviour can be reproduced on different Safari versions: - iOS 15.5 Safari - MacOS Safari Version 15.5 (17613.2.7.1.8) - MacOS Safari Technology Preview Release 146 (Safari 15.4, WebKit 17614.1.14.10.6) Current Firefox and Chrome versions behave correctly. Please see the attached reproduction example.

Oh, this is nothing to do with Shadow DOM.
