Thanks for filing, was on my list of things to do :)

As I said in the linked issue, I'd argue for keeping the consistency with existing APIs in regards of treating undeclared namespaces as invalid.

For example, right now `document.querySelector("a|b")` throws instead of returning null, for example. I think `CSS.supports` should do the same, and same `@supports` unless namespaces are registered in the style sheet.

This is both more consistent (IMO) and easier to implement / less special-casey.
