	class Step extends Evented {
	  /**
	   * Create a step
	   * @param {Tour} tour The tour for the step
	   * @param {object} options The options for the step
	   * @param {boolean} options.arrow Whether to display the arrow for the tooltip or not. Defaults to `true`.
	   * @param {object} options.attachTo The element the step should be attached to on the page.
	   * An object with properties `element` and `on`.
	   *
	   * ```js
	   * const step = new Step(tour, {
	   *   attachTo: { element: '.some .selector-path', on: 'left' },
	   *   ...moreOptions
	   * });
	   * ```
	   *
	   * If you don’t specify an attachTo the element will appear in the middle of the screen.
	   * If you omit the `on` portion of `attachTo`, the element will still be highlighted, but the tooltip will appear
	   * in the middle of the screen, without an arrow pointing to the target.
	   * @param {HTMLElement|string} options.attachTo.element An element selector string or a DOM element.
	   * @param {string} options.attachTo.on The optional direction to place the Popper tooltip relative to the element.
	   *   - Possible string values: 'auto', 'auto-start', 'auto-end', 'top', 'top-start', 'top-end', 'bottom', 'bottom-start', 'bottom-end', 'right', 'right-start', 'right-end', 'left', 'left-start', 'left-end'
	   * @param {Object} options.advanceOn An action on the page which should advance shepherd to the next step.
	   * It should be an object with a string `selector` and an `event` name
	   * ```js
	   * const step = new Step(tour, {
	   *   advanceOn: { selector: '.some .selector-path', event: 'click' },
	   *   ...moreOptions
	   * });
	   * ```
	   * `event` doesn’t have to be an event inside the tour, it can be any event fired on any element on the page.
	   * You can also always manually advance the Tour by calling `myTour.next()`.
	   * @param {function} options.beforeShowPromise A function that returns a promise.
	   * When the promise resolves, the rest of the `show` code for the step will execute.
	   * @param {Object[]} options.buttons An array of buttons to add to the step. These will be rendered in a
	   * footer below the main body text.
	   * @param {function} options.buttons.button.action A function executed when the button is clicked on.
	   * It is automatically bound to the `tour` the step is associated with, so things like `this.next` will
	   * work inside the action.
	   * You can use action to skip steps or navigate to specific steps, with something like:
	   * ```js
	   * action() {
	   *   return this.show('some_step_name');
	   * }
	   * ```
	   * @param {string} options.buttons.button.classes Extra classes to apply to the `<a>`
	   * @param {boolean} options.buttons.button.disabled Should the button be disabled?
	   * @param {string} options.buttons.button.label The aria-label text of the button
	   * @param {boolean} options.buttons.button.secondary If true, a shepherd-button-secondary class is applied to the button
	   * @param {string} options.buttons.button.text The HTML text of the button
	   * @param {boolean} options.canClickTarget A boolean, that when set to false, will set `pointer-events: none` on the target
	   * @param {object} options.cancelIcon Options for the cancel icon
	   * @param {boolean} options.cancelIcon.enabled Should a cancel “✕” be shown in the header of the step?
	   * @param {string} options.cancelIcon.label The label to add for `aria-label`
	   * @param {string} options.classes A string of extra classes to add to the step's content element.
	   * @param {string} options.highlightClass An extra class to apply to the `attachTo` element when it is
	   * highlighted (that is, when its step is active). You can then target that selector in your CSS.
	   * @param {string} options.id The string to use as the `id` for the step.
	   * @param {number} options.modalOverlayOpeningPadding An amount of padding to add around the modal overlay opening
	   * @param {number} options.modalOverlayOpeningRadius An amount of border radius to add around the modal overlay opening
	   * @param {object} options.popperOptions Extra options to pass to Popper
	   * @param {boolean|Object} options.scrollTo Should the element be scrolled to when this step is shown? If true, uses the default `scrollIntoView`,
	   * if an object, passes that object as the params to `scrollIntoView` i.e. `{behavior: 'smooth', block: 'center'}`
	   * @param {function} options.scrollToHandler A function that lets you override the default scrollTo behavior and
	   * define a custom action to do the scrolling, and possibly other logic.
	   * @param {function} options.showOn A function that, when it returns `true`, will show the step.
	   * If it returns false, the step will be skipped.
	   * @param {string} options.text The text in the body of the step. It can be one of three types:
	   * ```
	   * - HTML string
	   * - `HTMLElement` object
	   * - `Function` to be executed when the step is built. It must return one the two options above.
	   * ```
	   * @param {string} options.title The step's title. It becomes an `h3` at the top of the step. It can be one of two types:
	   * ```
	   * - HTML string
	   * - `Function` to be executed when the step is built. It must return HTML string.
	   * ```
	   * @param {object} options.when You can define `show`, `hide`, etc events inside `when`. For example:
	   * ```js
	   * when: {
	   *   show: function() {
	   *     window.scrollTo(0, 0);
	   *   }
	   * }
	   * ```
	   * @return {Step} The newly created Step instance
