title: How to prevent svg drag on specific element?
body: <p>I'm using the fantastic svg-pan-zoom plugin (<a href="https://github.com/ariutta/svg-pan-zoom" rel="nofollow">https://github.com/ariutta/svg-pan-zoom</a>) to pan/zoom my svg element, I want to enable the mouse drag to let use move it.</p>
  
  <p>I have a single  elemen inside my svg where I want to prevent the drag because it has a click event and when the user clicks on it sometimes it drag the svg element.
  The requested behavior is to drag as standard except when the mouse is down on this element.
  I already try with event.stopPropagation() and event.preventDefault() but seems that svg-pan-zoom plugin has its own event management.</p>
  
  <p>How can I prevent the mouse drag?</p>
