Created attachment 466673 [details] example.html When submitting a form with validation errors, the :user-invalid dirty state is reset. When resetting a form, it is not. In the attached form, dirty the 'not-an-email' field with an invalid email address. The border will become red on blur. If clicking the submit button, the form will fail validation but the red border will clear. If clicking the reset button, the email field will return to its starting value but maintain the red border. I'd expect these behaviours to be reversed. That is submitting a form does not clear the dirty tracking and resetting a form does.
