Re: [csswg-drafts] [selectors] pseudo selector to match forms ValidityState (#1525)

> Assuming following best-practice and associating the message with the input for AT (`aria-describedby`), how does this ensure multiple messages aren't sent to the axTree?

The pseudo-classes don't have any effect on the accessibility tree. They are only used to match form fields that are in a specific invalid state.
