-   * - `px` or unitless, interpreted as pixels
-   * - `%` or `%r`, percentage relative to the length of the reference element
-   * - `%p`, percentage relative to the length of the popper element
-   * - `vw`, CSS viewport width unit
-   * - `vh`, CSS viewport height unit
-   *
-   * For length is intended the main axis relative to the placement of the popper.<br />
-   * This means that if the placement is `top` or `bottom`, the length will be the
-   * `width`. In case of `left` or `right`, it will be the height.
-   *
-   * You can provide a single value (as `Number` or `String`), or a pair of values
-   * as `String` divided by a comma or one (or more) white spaces.<br />
-   * 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.
-   *
-   * Valid examples are:
-   * ```
-   * 10
-   * '10%'
-   * '10, 10'
-   * '10%, 10'
-   * '10 + 10%'
-   * '10 - 5vh + 3%'
-   * '-10px + 5vh, 5px - 6%'
-   * ```
-   * > **NB**: If you desire to apply offsets to your poppers in a way that may make them overlap
-   * > with their reference element, unfortunately, you will have to disable the `flip` modifier.

-  *			left(-start, -end)`
-  * @param {HTMLElement|String|false} options.container=false - Append the tooltip to a specific element.
-  * @param {Number|Object} options.delay=0
-  *			Delay showing and hiding the tooltip (ms) - does not apply to manual trigger type.
-  *			If a number is supplied, delay is applied to both hide/show.
-  *			Object structure is: `{ show: 500, hide: 100 }`
-  * @param {Boolean} options.html=false - Insert HTML into the tooltip. If false, the content will inserted with `innerText`.
-  * @param {String|PlacementFunction} options.placement='top' - One of the allowed placements, or a function returning one of them.
-  * @param {String} [options.template='<div class="tooltip" role="tooltip"><div class="tooltip-arrow"></div><div class="tooltip-inner"></div></div>']
-  *			Base HTML to used when creating the tooltip.
-  *			The tooltip's `title` will be injected into the `.tooltip-inner` or `.tooltip__inner`.
-  *			`.tooltip-arrow` or `.tooltip__arrow` will become the tooltip's arrow.
-  *			The outermost wrapper element should have the `.tooltip` class.
-  * @param {String|HTMLElement|TitleFunction} options.title='' - Default title value if `title` attribute isn't present.
-  * @param {String} [options.trigger='hover focus']
-  *			How tooltip is triggered - click, hover, focus, manual.
-  *			You may pass multiple triggers; separate them with a space. `manual` cannot be combined with any other trigger.
-  * @param {HTMLElement} options.boundariesElement
-  *			The element used as boundaries for the tooltip. For more information refer to Popper.js'
-  *			[boundariesElement docs](https://popper.js.org/popper-documentation.html)

-  *			[offset docs](https://popper.js.org/popper-documentation.html)
-  * @param {Object} options.popperOptions={} - Popper options, will be passed directly to popper instance. For more information refer to Popper.js'
