Template relation doesn't appear on graph

[Sblawy]

Describe the bug
While using doxygen to generate relation graph, the templated element appear but the link (orange arrow) with the base template is not present.
In the next example, the 2 structs have the template but only one appear in graph.
The only one who appear is the one who extends the templated class.

Screenshots

To Reproduce
The Doxyfile is attached to the issue, and the code used in sceen is here :

namespace test_package {
  struct T_1;
  struct T_2;
  template <typename T> struct TemplaceStruct {};

  struct HeritedStruct1: public TemplaceStruct<T_1> {
    static int getValue()
    {
      return 1;
    }
  };

  struct TemplaceStruct<T_2> {
    static int getValue()
    {
      return 2;
    }
  };
}

Expected behavior
In this case, the orange arrow to identify the template need to appear for struct TemplaceStruct<T_2>.
Ideally, having a page with all relationships (inheritance and template) will be a most.

The Doxyfile is attached to the issue

Sorry I don't see the Doxyfile please add it, actually better:

• Can you please attach a, small, self contained example (source+configuration file in a, compressed, tar or zip file!) that allows us to reproduce the problem? Please don't add external links as they might not be persistent (also references to GitHub repositories are considered non persistent).

Excuse me, I possibly do an error when I add the Doxyfile.
Here is attached a zip file with source code, Doxyfile and the documentation generate by doxygen.
