AlgebraicGeometry.Scheme.PartialMap.comp_equiv_of_equiv_left

∀ {X Y Z : AlgebraicGeometry.Scheme} [inst : PreirreducibleSpace ↥X] [inst_1 : Nonempty ↥Y] {f₁ f₂ : X.PartialMap Y}
  [inst_2 : AlgebraicGeometry.IsDominant f₁.hom] [inst_3 : AlgebraicGeometry.IsDominant f₂.hom],
  f₁.equiv f₂ → ∀ (g : Y.PartialMap Z), (f₁.comp g).equiv (f₂.comp g)

Composition respects equivalence of partial maps on the left.
