/**
 * Returns boolean indicating whether the given element has a role
 * that is associated with a non-interactive component. Non-interactive roles
 * include `listitem`, `article`, or `dialog`. These are roles that indicate
 * for the most part containers.
 *
 * Elements with these roles should not respond or handle user interactions.
 * For example, an `onClick` handler should not be assigned to an element with
 * the role `listitem`. An element inside the `listitem`, like a button or a
 * link, should handle the click.
 *
 * This utility returns true for elements that are assigned a non-interactive
 * role. It will return false for elements that do not have a role. So whereas
 * a `div` might be considered non-interactive, for the purpose of this utility,
 * it is considered neither interactive nor non-interactive -- a determination
 * cannot be made in this case and false is returned.
