Re: [csswg-drafts] [selectors-4] Issue 11: Introduce pseudo-class matching when user changed the value of an input (#1533)

This would be really useful for creating [material style](https://material.angular.io/components/input/overview) inputs that move the label of the input above it.. Most implementations I've seen either use JavaScript or take advantage of the `required` attribute along with the `:valid` selector, but obviously this isn't ideal.
