ASDoc @inheritDoc if copies from another @inheritDoc dulicates content

Steps to reproduce:
1. Create an interface IFoo with a method bar().
2. Document method bar() in interface.
3. Implement interface in class Foo.
4. Document implemented method bar() with @inheritDoc.
5. Extend class Foo in class FooExtended and override method bar().
6. Document overridden method bar() with @inheritDoc comment.
7. Compile documentation.
8. ???
9. The documentation for overridden method bar() in class FooExtended is repeated twice!

Actual Results:
The documentation is duplicated (sometimes more then once).

Expected Results:
The documentation should not repeat if inherited from a superclass.

Workaround (if any):
It seems it is possible to work around it with @copyDoc.
