title: ConstraintLayout cannot scale down chained ImageViews
body: <p>I've created a simple layout containing two ImageViews and one TextView. ImageViews need to be placed horizontally next to each other. I tried to use a spread chain to achieve that but ImageViews cannot be scale down to fit the screen.</p>

  <p><strong>EDIT</strong></p>
  
  <p>When i used a nested LinearLayout it works as i want it to work. </p>
