The compartments aren't not well resized when the node is resized in width

Steps to reproduce:

1. Create a new ClassDiagram
2. Create a Class
3. Change the height of its compartment
4. Resize the Class in width.

Now you get Compartments which doesn't fill all the available width.

This issue is also reproductible on many nodes.

This issue can also be reproduced with Symbol Compartment on Component node and Package nodes (and probably others nodes not yet identified)
