title: Using DHTMLX Scheduler, prevent tooltips from disappearing when hovering out of the event to the tooltip
body: <p>I have been using the excellent DHTMLX Scheduler for a few days to get on with it, and I found solutions and workarounds for almost every specific things I wanted to achieve.</p>
  
  <p>However, in this particular case, I am using the extension that allows tooltip customisation when hovering on an event (<a href="http://docs.dhtmlx.com/scheduler/tooltips.html" rel="nofollow">see doc here</a>) which is working fine. </p>
  
  <p>My problem here is the tooltip disappears when hovering out of the event, which is not wrong. The thing is I want to add clickable content in the tooltip, but since it disappears this simple task is rendered impossible.</p>
  
  <p>I've searched through the docs, various forums and even here, but I haven't found any help regarding that matter.</p>
  
  <p>Long story short, how can I prevent tooltips from disappearing when hovering above the tooltip itself (if at all possible)?</p>
  
  <p>Thank you anyway.</p>
