> The :user-invalid and the :user-valid pseudo-classes represent an element with incorrect or correct input, respectively, but only after the user has significantly interacted with it.

"significant user interaction" here is implemented as the first time the change event is emitted for a control, which is in practice
represents when the user has finished entering a value then moves focus away from the element. This matches Firefox's behavior.

User-initiated form submissions reset the state as the CSSWG spec says.

Based on patch by Devin Rousso.
