 *
 * - 'title[role="heading"]' queries for elements with name 'title' and role 'heading'.
 * - '[role="img"]' queries for elements with role 'img' and any name.
 * - 'label' queries for elements with name 'label' and any role.
 * - '[name=""][role="button"]' queries for elements with no name and role 'button'.
