Nested generics with class name definitions on ClassDiagram

[kairi003]

Description

Hi, I have discovered that there is a non-functioning demo on the local demo page in the development environment:
https://github.com/kairi003/mermaid/blob/115cb071b09056c34c9b750579432d4232a10500/demos/classchart.html#L148-L160

    <pre class="mermaid">
    classDiagram
      class Person {
        +Id : Guid
        +FirstName : string
        +LastName : string
        -privateProperty : string
        #ProtectedProperty : string
        ~InternalProperty : string
        ~AnotherInternalProperty : List~List~string~~
      }
      class People List~List~Person~~
    </pre>

L159 probably defines a class named PeopleList<List<Person>>, but it does not work.

Nesting of Generic Types by ~ works for members, but not for class name definitions.

Not nested case: class People List~List~

classDiagram
  class People List~List~

Nested case: class People List~List~Person~~

classDiagram
  class People List~List~Person~~

Setup

• Mermaid version: develop branch, commit #115cb071b09056c34c9b750579432d4232a10500
• Browser and Version: Chrome

Suggested Solutions

• classDiagram.jison needs to be modified to allow nested generics
• classDb.ts > splitClassNameAndType() needs to be modified to properly parse nested generics (using parseGenericTypes()?)

Additional Context

I’m a beginner with both this project and Jison. I apologize, but I’m hoping someone can help resolve this.
