title: Fullcalendar prevent eventDidMount triggers constanty while dragging
body: <p>I have a Tippy.js integrated into a FullCalendar.js calendar.
  While dragging an event inside the calendar, the tooltips get crazy, losing reference to the event that triggered it.</p>
  <p>I think the issue is that I'm creating the Tippy (tooltip) instance inside the <code>eventDidMount</code> hook, and this being call while dragging every time the dragged event is snaped to a calendar cell, and that is why it triggers lots of tooltips in the process.</p>
  <p>Fullcalendar has a hook for <code>eventDragStart(eventInfo)</code> but I don't know how to get to the attached tippy instance to hide it. Or should I prevent creating a tooltip at all while dragging instead?</p>
  <pre><code> //Other FullCalendar Initialization
   ...
   eventDidMount: function(info) {
       tippy(info.el, {
          interactive: true, 
          delay: 300,
          theme: 'light-border',
          maxWidth: 400,
          allowHTML: true,
          appendTo: document.getElementById('mainContent'),   
          content(reference) {
              //Tooltip content
              return tempRendered;
          },
        });                                     
   }
   eventDragStart(info){
     //I SUPPOSE HERE I SHOULD DO SOMETHING TO HIDE THE TIPPY TOOLTIP
   }
  </code></pre>
  <p>Any ideas?</p>
