For the imported/blink/fast/forms/textarea-placeholder-visibility-3.html failure, it seems like we need to call TextControlPlaceholderElement::resolveCustomStyle(). Not sure if this is an isolated case where Style::PseudoClassChangeInvalidation is not enough compared to invalidateStyleForSubtree(), but might be worth checking. In the meantime, I've added this for the placeholder case: if (RefPtr placeholder = placeholderElement()) placeholder->invalidateStyle();
