classDiagram - New version fails in some relationships

[gcosta87]

Describe the bug
The new version of Mermaid changed the way some relationships are rendered in classDiagram. Especially the relationships of a class to itself.
On the other hand, and being less critical, in large diagrams with namespaces, those classes that have several relationships with others, tend to overlap more frequently.

To Reproduce
Just render this example diagram

classDiagram
   class MyClass {
    value: String
   }

   MyClass o--> "0..N" MyClass: blocks
   MyClass o--> "0..N" MyClass: require

To reproduce the other (less severe) bug requires a large diagram (30 classes and some namespaces)

Expected behavior
The MyClass class has two clear relationships with itself: blocks and requires.

Additional context
I notice this change when I have an active class design project, and I usually compare it with the VSCode rendering (which uses an older version of the mermaid engine)
