title: ConstraintLayout chain context menu no longer visible in Android Studio
body: <p>Using Android Studio 3.4 Canary 9 and 10
  ConstraintLayout 2.0.0.alpha3</p>
  
  <p>I am having an issue with constraint layout in the bleeding edge build of Android Studio 3.4 canary 9. Basically, when you click on a view in constraint layout, say on a chain element, you should be able to see small icons appear that allow you to perform certain actions on the views.</p>

  <p>As you can see, under each view are 3 buttons that allow you to change the chain settings. However, this is what I get in my layout editor on 3.4.C09 when clicking on an element in a chain:</p>

  <p>Did they get disabled or moved elsewhere? Is this a bug? I have looked everywhere in the IDE without any luck, tried zooming in / zooming out, changing the theme, invalidating caches/restart, clean rebuild etc.</p>
  
  <p>Thank you for any help provided!</p>
