With the following code:
  class A {
    f() { }
  }
  class B extends A {
    f() {
      super.f();
    }
  }
  class C extends B {
    f() {
      super.f();
    }
  }

"Find uses" on A.f() shows B.f() and C.f(). This is incorrect--C.f() does not call A.f().
"Find uses" on B.f() shows B.f() and C.f(). This is incorrect--B.f() does not call itself.
"Find uses" on C.f() shows B.f() and C.f(). This is incorrect--neither B.f() nor C.f() calls C.f().

It appears that "find uses" is failing to account for the fact that super invocations are not dynamic--they look up the callee in the superclass of the immediately enclosing class, regardless of the dynamic type of the object.
