You're mistaken. For the purpose of grammar parsing, whitespace is always ignored, unless there's prose specifically defining that it is significant in some way. So in `@media {...}`, the `<media-query-list>` production is just an empty list of tokens. The parsing rules then run on it, producing an empty list.
This is implied by <https://drafts.csswg.org/css-values/#component-whitespace>, tho it could perhaps be a little clearer.
