title: ConstraintLayout 1.0.2 shows nothing
body: <p>I'm still having this weird problem. ConstraintLayout only works when it's on 'alpha-7', when I change it to '1.0.2' the latest version it shows nothing</p>
  
  <p>Desired layout should look like this:</p>

  <p>However, I'm getting this: "on a real HTC one M9 - CM 12.1.1"</p>

  <p>** I also tried with 'Show layout update' and it shows nothing as well</p>
