FractionalIdeal.count_self

∀ {R : Type u_1} [inst : CommRing R] (K : Type u_2) [inst_1 : Field K] [inst_2 : Algebra R K]
  [inst_3 : IsFractionRing R K] [inst_4 : IsDedekindDomain R] (v : IsDedekindDomain.HeightOneSpectrum R),
  FractionalIdeal.count K v ↑v.asIdeal = 1

val_v(v) = 1, when v is regarded as a fractional ideal.
