   *
   * Attaches all registered behaviors to a page element.
   *
   * Behaviors are event-triggered actions that attach to page elements,
   * enhancing default non-JavaScript UIs. Behaviors are registered in the
   * {@link Drupal.behaviors} object using the method 'attach' and optionally
   * also 'detach'.
   *
   * {@link Drupal.attachBehaviors} is added below to the `jQuery.ready` event
   * and therefore runs on initial page load. Developers implementing Ajax in
   * their solutions should also call this function after new page content has
   * been loaded, feeding in an element to be processed, in order to attach all
   * behaviors to the new content.
   *
   * Behaviors should use `var elements =
   * $(context).find(selector).once('behavior-name');` to ensure the behavior is
   * attached only once to a given element. (Doing so enables the reprocessing
   * of given elements, which may be needed on occasion despite the ability to
   * limit behavior attachment to a particular element.)
   *
   * @example
   * Drupal.behaviors.behaviorName = {
   *   attach: function (context, settings) {
   *     // ...
   *   },
   *   detach: function (context, settings, trigger) {
   *     // ...
   *   }
   * };
   *
   * @param {HTMLDocument|HTMLElement} [context=document]
   *   An element to attach behaviors to.
   * @param {object} [settings=drupalSettings]
   *   An object containing settings for the current context. If none is given,
   *   the global {@link drupalSettings} object is used.

   *
   * Such implementations should use `.findOnce()` and `.removeOnce()` to find

   * is detached only from previously processed elements.

   * @param {string} [trigger='unload']
   *   A string containing what's causing the behaviors to be detached. The
   *   possible triggers are:
   *   - `'unload'`: The context element is being removed from the DOM.
   *   - `'move'`: The element is about to be moved within the DOM (for example,
   *     during a tabledrag row swap). After the move is completed,
   *     {@link Drupal.attachBehaviors} is called, so that the behavior can undo
   *     whatever it did in response to the move. Many behaviors won't need to
   *     do anything simply in response to the element being moved, but because
   *     IFRAME elements reload their "src" when being moved within the DOM,
   *     behaviors bound to IFRAME elements (like WYSIWYG editors) may need to
   *     take some action.
   *   - `'serialize'`: When an Ajax form is submitted, this is called with the
   *     form as the context. This provides every behavior within the form an
   *     opportunity to ensure that the field elements have correct content
   *     in them before the form is serialized. The canonical use-case is so
   *     that WYSIWYG editors can update the hidden textarea to which they are

   * Prevents consecutive form submissions of identical form values.

   * Repetitive form submissions that would submit the identical form values

   *
   * This is a simplified re-implementation of a user-agent behavior that
   * should be natively supported by major web browsers, but at this time, only
   * Firefox has a built-in protection.
   *
   * A form value-based approach ensures that the constraint is triggered for
   * consecutive, identical form submissions only. Compared to that, a form
   * button-based approach would (1) rely on [visible] buttons to exist where
   * technically not required and (2) require more complex state management if
   * there are multiple buttons in a form.
   *
   * This implementation is based on form-level submit events only and relies
   * on jQuery's serialize() method to determine submitted form values. As such,
   * the following limitations exist:
   *
   * - Event handlers on form buttons that preventDefault() do not receive a
   *   double-submit protection. That is deemed to be fine, since such button
   *   events typically trigger reversible client-side or server-side
   *   operations that are local to the context of a form only.
   * - Changed values in advanced form controls, such as file inputs, are not
   *   part of the form values being compared between consecutive form submits
   *   (due to limitations of jQuery.serialize()). That is deemed to be
   *   acceptable, because if the user forgot to attach a file, then the size of
   *   HTTP payload will most likely be small enough to be fully passed to the
   *   server endpoint within (milli)seconds. If a user mistakenly attached a
   *   wrong file and is technically versed enough to cancel the form submission
   *   (and HTTP payload) in order to attach a different file, then that
   *   edge-case is not supported here.
   *
   * Lastly, all forms submitted via HTTP GET are idempotent by definition of
   * HTTP standards, so excluded in this implementation.
