title: DoTween repeatType.yoyo not working inside Sequence
body: <p>I am using DoTween and have a <code>Sequence</code> to scale a button from 0 to 1 and then pulse the scale from 1 to 1.25 looped.</p>
  
  <p>My problem is that the loop inside the <code>Sequence</code> does not work. It will go to scale 1 and then to 1.25 but stop there.</p>
  
  <p>If I just run the loop outside the <code>Sequence</code> it works fine.</p>
  
  <pre><code>DOTween.Sequence()
     .Append(playButton.transform.DOScale(new Vector3(1f, 1f, 1), 1f).SetEase(Ease.OutBack))
     .Append(playButton.transform.DOScale(new Vector3(1.25f, 1.5f, 1), 1f).SetEase(Ease.Linear).SetLoops(-1, LoopType.Yoyo))
     .SetAutoKill(false);
  </code></pre>
