This is because the change events were being dispatched before > + form validity was updated. Making the validation step come before the change event dispatch fixes > + this issue. Normally the Test line comes last. > LayoutTests/fast/forms/onchange-select-check-validity.html:17 > + select.onchange = showFormValidity; > + select.addEventListener("change", showFormValidity); I think these two lines do the same thing. You only need one of them.
