 * out of the object anyway, which makes the short form and the full form equivalent. Passing them all keeps one rule
 * here instead of a per-control opinion about which flags are worth naming.
 *
 * @param control The native control rendered inside the component's shadow root.
 * @param customValidity The component's current custom validity message, or an empty string when none is set.
