/**
   * A JavaScript module that enhances a button and text container to support copy-to-clipboard functionality.
   *
   * This module needs to be loaded by pages/templates/modules that require this functionality.
   *
   * To enable copy-to-clipboard functionality, we need a trigger element (usually a button) and a copy target element
   * (e.g. a div, span, text input, or text area).
   *
   * In the trigger element, we need to declare the <code>data-action="copytoclipboard"</code> attribute and set the
   * <code>data-clipboard-target</code> attribute which is the CSS selector that points to the target element that contains the text
   * to be copied.
   *
   * When the text is successfully copied to the clipboard, a toast message that indicates that the copy operation was a success
   * will be shown. This success message can be customised by setting the <code>data-clipboard-success-message</code> attribute in the
   * trigger element.
