/**
   * This module provides change detection to forms, allowing a browser to warn the user before navigating away if changes
   * have been made.
   *
   * Two flags are stored for each form:
   * * a 'dirty' flag; and
   * * a 'submitted' flag.
   *
   * When the page is unloaded each watched form is checked. If the 'dirty' flag is set for any form, and the 'submitted'
   * flag is not set for any form, then a warning is shown.
   *
   * The 'dirty' flag is set when any form element is modified within a watched form.
   * The flag can also be set programatically. This may be required for custom form elements.
   *
   * It is not possible to customise the warning message in any modern browser.
   *
   * Please note that some browsers have controls on when these alerts may or may not be shown.
   * See {@link https://developer.mozilla.org/en-US/docs/Web/API/WindowEventHandlers/onbeforeunload} for browser-specific
   * notes and references.
