--- Comment #6 from Patrick Palka <ppalka at gcc dot gnu.org> ---
I wonder if adding a non-static overload of FromWebContents should affect the
dependent-ness of guest, e.g.:

class A {
public:
  template <typename> void As();
  static A *FromWebContents();
  template <typename... Ts>
  A *FromWebContents(Ts...);
};
template <typename T> class B : A {
  void FromWebContents() {
    auto guest = A::FromWebContents();
    guest->As<T>();
  }
};
