Enum type inferred as never when using Type.Mapped()

[tchyra]

Reproduction:

enum E { O1, O2 }

const T = Type.Object({ a: Type.Enum(E) });                     // TObject<{ a: TEnum<typeof E> }>
type T = Static<typeof T>;                                      // { a: E }

const U = Type.Mapped(Type.KeyOf(T), K => Type.Index(T, K));    // TObject<{ a: TUnion<[]> }>
type U = Static<typeof U>;                                      // { a: never; }

Thank you for your work on Typebox, it's proven quite useful :)
