PSI to FIR association issue: Incorrect on parent classes.

                  class A {
                      class B {
                          class C
                      }
                  }
                  val c = A.B.C()

Both A and B will have the same type, A$B.

This is hard to resolve since A.B is the minimum granularity in the FIR, say it's like atomic from the FIR perspective, so distinguishing between A and B or more will require some additional algorithm on the FIR to break down the atomic nucleus into quarks. this is a even harder case than above

              class A {
                  class B {
                      class A {
                          class C
                      }
                  }
              }

              val x = A.B.A.C()
