[selectors] Misplaced paragraph about default namespace protection

[markbrown]

https://drafts.csswg.org/selectors-4/#matches contains these paragraphs:

Default namespace declarations do not affect the compound selector representing the subject of any selector within a :matches() pseudo-class, unless that compound selector contains an explicit universal selector or type selector.

As with :matches(), default namespace declarations do not affect the compound selector representing the subject of any selector within a :matches() pseudo-class, unless that compound selector contains an explicit universal selector or type selector.

The second paragraph doesn't make sense here. :not() has a similar paragraph, so perhaps this one was intended for :has()?
