Steps to reproduce

1. create View
2. create Diagram Description and a domain based Edge with a begin label and an end label
3. create a model and a Diagram based on step 2
4. create elements to get two diagram nodes and a diagram edge between the diagram nodes
5. try to move one of the diagram nodes

Expected behavior

The begin label and the end label are moving smoothly while the node is moving. When the user finishes to move the node, the begin label and the end label locations are near the nodes.
It seems to already work for the "middle" label of an edge. May be applying the same algorithm for the begin label and the end label would be enough.

Actual behavior

The begin label and the end label are moving weirdly while the node is moving. When the user finishes to move the node, the begin label and the end label locations are far from the nodes.
