[csswg-drafts] [selectors] :link and :visited are not mutually exclusive in implementations

victoriasu has just created a new issue for https://github.com/w3c/csswg-drafts:

== [selectors] :link and :visited are not mutually exclusive in implementations ==
According to the [spec](https://drafts.csswg.org/selectors-4/#link), :link and :visited should be mutually exclusive, however in:
Chrome, Firefox, and Safari
- Style rules for :link and :visited are being applied to the same element (a visited link)
Edge
- All links are using the :link style and not the :visited style

Tested using:
