* Creates a debounced function that delays invoking `func` until after `wait`
* milliseconds have elapsed since the last time the debounced function was

* Provide `options` to indicate whether `func` should be invoked on the
* leading and/or trailing edge of the `wait` timeout. The `func` is invoked

* invoked on the trailing edge of the timeout only if the debounced function
* is invoked more than once during the `wait` timeout.

* until to the next tick, similar to `setTimeout` with a timeout of `0`.

* - `%p`, percentage relative to the length of the popper element
* - `vw`, CSS viewport width unit

* This means that if the placement is `top` or `bottom`, the length will be the

* The latter is a deprecated method because it leads to confusion and will be
* removed in v2.<br />
* Additionally, it accepts additions and subtractions between different units.
* Note that multiplications and divisions aren't supported.

*/class Ri extends Vo{/**
* Create a step
* @param {Tour} tour The tour for the step
* @param {Object} options The options for the step
* @param {Object|string} options.attachTo What element the step should be attached to on the page.
* It can either be a string of the form "element on", or an object with those properties.
* For example: ".some #element left", or {element: '.some #element', on: 'left'}.
* If you use the object syntax, element can also be a DOM element. If you don’t specify an attachTo the
* element will appear in the middle of the screen.
* @param {HTMLElement|string} options.attachTo.element
* @param {string} options.attachTo.on
* @param {Object|string} options.advanceOn An action on the page which should advance shepherd to the next step.
* It can be of the form `"selector event"`, or an object with those properties.
* For example: `".some-element click"`, or `{selector: '.some-element', event: 'click'}`.
* It 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
* @param {string} options.buttons.button.classes Extra classes to apply to the `<a>`
* @param {Object} options.buttons.button.events A hash of events to bind onto the button, for example
* `{'mouseover': function(){}}`. Adding a `click` event to events when you already have an `action` specified is not supported.
* You can use events to skip steps or navigate to specific steps, with something like:
* ```js
* events: {
* click: function() {
* return Shepherd.activeTour.show('some_step_name');
* }
* }
* ```
* @param {string} options.buttons.button.text The HTML text of the button
* @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 {Object} options.tippyOptions Extra [options to pass to tippy.js]{@link https://atomiks.github.io/tippyjs/#all-options}
* @param {boolean} options.scrollTo Should the element be scrolled to when this step is shown?
* @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 {boolean} options.showCancelLink Should a cancel “✕” be shown in the header of the step?
* @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 four types:
* ```
* - HTML string
* - Array of HTML strings
* - `HTMLElement` object
* - `Function` to be executed when the step is built. It must return one of the three options above.
* ```
* @param {string} options.title The step's title. It becomes an `h3` at the top of the step.
* @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
