title: scale div and adapt his parent size
body: <p>I've this code : <a href="https://jsfiddle.net/56pghvt6/" rel="nofollow noreferrer">https://jsfiddle.net/56pghvt6/</a>
  I want my parent height adapt to his visible content but when I apply a <code>transform: scaleY(0)</code> to the child div. Actually parent height don't change.</p>
  
  <p>precision : I use ScaleY to animate a mouse hover, so <code>display: none</code> are not a solution</p>
  
  <p>Any idea to solve the problem ?</p>
