title: problem with wavesurfer-js intract with preloaded peaks
body: <p>There was a problem for me that I couldn't find the answer to</p>
  
  <p>Although I set the value of "interact" to "true", it clicks on the sound wave play from the beginning</p>
  
  <p>my constructor:</p>
  
  <pre><code>audioContext: audiocontext,
  container: soundWaveContainers[index],
  waveColor: "#999",
  progressColor: "#00ffaf",
  cursorColor: "#999",
  height: 52,
  mediaType: "audio",
  normalize: false,
  hideScrollbar: false,
  mediaControls: true,
  interact: true,
  backend: "MediaElement",
  </code></pre>
  
  <p>load:</p>
  
  <pre><code>wavesurfer.load(streamURL, soundPeaks);
  </code></pre>
