* @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)
* @param {Number|String} options.offset=0 - Offset of the tooltip relative to its reference. For more information refer to Popper.js'
