 * A loading button ignores activation but keeps keyboard focus: native
 * `disabled` would drop focus to the page. The click is stopped as it
 * starts, before any handler runs (an `asChild` child's own too), and
 * cancelled, so a submit does not send and a link does not navigate.
 * Presses, Enter and Space skip the given handlers, so a menu trigger
 * wrapped round the button does not open. Other keys still reach them,
 * so a roving group round it keeps its arrow keys and Shift+Tab. Spread
 * the result onto the button, with `aria-disabled` set while loading.
