Quick video to show the freeze

As the quick video shows, if you move the target arrow as far as right by dragging  a bendpoint, the edge stop moving (UI freeze).
You will be able to move the edge again if you drop, then drag again the bendpoint.

Steps to reproduce: 
* Create an Ecore Modeling Project (requires Ecore Tools)
* Create a class diagram on the root EPackage
* Create two classes and add one as super type of the other
* Play with the bendpoints as described by Guillaume: if you move the target arrow as far as right by dragging  a bendpoint, the edge stop moving (UI freeze).

This seems to be related to the Tree style.
