Describe the bug
base class function in code block no longer linked if the code block contains a derived class definition calling the base class function in Doxygen 1.9.5 or later

/**
 * \code
 * class Derived : public Base {
 *   void test() {
 *     fun();
 *   }
 * };
 * \endcode
 */
class Base {
public:
  /**
   * virtual function
   */
  virtual void fun();
};

Screenshots
Doxygen 1.9.4:

fun() is a link.

Doxygen 1.9.5 - trunk (3192bd6):

fun() is not a link

To Reproduce

Expected behavior
