title: Youtube player JS API seekTo function not working
body: <p>I'm trying to use Youtube chromeless player through the JS API and I'm having problems with seekto() function.</p>
  
  <p>The problem is that sometimes (I can't tell when the problem arises), calling seekTo() function backwards to a point in the video that is not loaded don't come back and instead stays in the current time.</p>
  
  <p>This is what I do (imagine the video is 240 seconds length):</p>
  
  <ol>
  <li>I start playing a video -> loadVideoById().</li>
  <li>I move forward to (let's say) the middle of the video -> seekTo(120)</li>
  <li>Video jumps correctly to the position I asked.</li>
  <li>I try to move backwards to 25% time of the video -> seekTo(60)</li>
  <li>Sometimes the video jumps back to 60 but more often it only goes back to 120.</li>
  </ol>
  
  <p>So, is anyone else having this issue?</p>
