Android Studio version: 4.0.0-canary1
Libraries used: ConstraintLayout 2.0.0-beta-3

I tried to DnD views onto a Flow Helper on the Component tree. The first time, the dragged view simply disappeared. After Undoing and trying again nothing happens.

Hi, the Flow Helper is not a ViewGroup, I think you cannot drag a View into it?

Flow is a constraint helper. As per the doc:
> The elements referenced are indicated via constraint_referenced_ids, as with other ContraintHelper implementations.

Like for Barrier, dragging a view onto a Flow element should add the id of the view to the list of constraint_referenced_ids
