title: How to reset the timer of SVG animation when using beginElementAt()?
body: <p>I use <code>elt.beginElementAt(-5)</code> on SVG animation with dur="10s", it's worked in 5s, normal.
  BUT if at the end of an animation (i.e. at 5 seconds after launch <code>elt.beginElementAt(-5)</code> cmd) I want to trigger it again, It doesn't work! </p>
  
  <p>I have to wait for the "truth" duration (10s in this example), to be able to restart the animation. Nothing happens if I try between 5s and 10s after my first <code>elt.beginElementAt(-5)</code> command...</p>
  
  <p>So, how to reset the timer? How to ignore the "normal" duration?</p>
  
  <p>Thanks.</p>
