Selectors 4 says "an element that is the source anchor of a hyperlink 
whose target's absolute URL matches the element's own document URL."

So the href attribute value would be parsed as an URL and made absolute 
per the usual rules before being matched by :link-local. In an HTML 
document, without a <base> element, the base URL would be the document 
URL and so :link-local would match.

I agree that Selectors 4 should be changed here. URLs that differ only 
by the scheme or port number should not be considered "local".
