title: fabricjs smaller object selection when placed over larger objects
body: <p>I am using fabric.js, when I have a smaller object (w.r.t height and width or scaled to be smaller) placed over a bigger object, I am unable to select the smaller object on click</p>
  
  <p>I have even tried the following,it solves my selectable problem, but the drawback is I lose the scaling at the bounding corners, I am unable to scale the object after implementing the below.</p>
  
  <p>You may try the same onto the following urlhttp://fabricjs.com/events/ check my screenshot attached, I have scaled the red square and placed a smaller green square over it. Once this placement is complete I am unable to select the green square.</p>
  
  <p>canvas.on('mouse:up', function(e) {</p>
  
  <pre><code>canvas.setActiveObject(canvas.item(e.target));
  </code></pre>
  
  <p>});</p>
