title: Tooltip remains on page when changing views from rowClick
body: <p>I am having issues with AnyGantt library. I have set the following eventListener:</p>
  
  <pre><code>  chart.listen(anychart.enums.EventType.ROW_CLICK, function(event) {
                  var programID = event['item'].get('id');
                  $state.go(..);
              });
  </code></pre>
  
  <p>And it does work - it redirects me to the webpage I want. However, there is an issue that really bothers me - there is a tooltip, that has not been deleted - it is added to the bottom of my html style, and I cannot find a way to get rid of it. Any help is more than appreciated!</p>
