title: Angular tooltip should stay open when hovered
body: <p>How can I achieve that a tooltip (angular/bootstrap UI) stays open when using "hover" as a trigger?</p>
  
  <p>Using "mouseover" I get better behaviour (tooltip stays open until I reenter the element where tooltip had been assigned to).</p>
  
  <p>EDIT: the same issue came up with JQUERY a while ago, please see here:
  <a href="https://stackoverflow.com/questions/10085773/jquery-tooltip-that-stays-open-on-hover">Jquery tooltip that stays open on hover</a></p>
  
  <p>That is exactly what I want to do with angular (as I cannot use JQuery).</p>
