In Firefox that rule is [built into](https://searchfox.org/mozilla-central/rev/4d2a9d5dc8f0e65807ee66e2b04c64596c643b7a/third_party/rust/cssparser/src/tokenizer.rs#857-861) [the tokenizer](https://searchfox.org/mozilla-central/rev/4d2a9d5dc8f0e65807ee66e2b04c64596c643b7a/third_party/rust/cssparser/src/tokenizer.rs#1383-1394), which is why it applies regardless of where the selector comes from.

I don't know why the rule wouldn't apply for the selectors coming from querySelector / other DOM APIs.
