The @[reducible] attribute on `Function.Surjective` is apparently not needed, and currently prevents `@[simp]` lemmas with `Function.Surjective` side conditions from firing, see [zulip discussion](https://leanprover.zulipchat.com/#narrow/stream/287929-mathlib4/topic/simp.20lemmas.20with.20side.20conditions).
