Barrier is not worked properly in Design or Blueprint view

[isem-dev]

android.support.constraint.Barrier is not worked properly on Andoid Studio 3.5.3 Layout editor -> Design or Blueprint view.

Steps to reproduce: Select two textView in your Component Tree. Drag both onto your barrier in the Component Tree. When you do this you're specifying that the barrier should float based on the position of both labels. In this step both textView disappears on Component Tree and its editing on Design or Blueprint view impossible.
