Current and expected behavior

Current:

var Animals = /*#__PURE__*/function (Animals) {
  Animals[Animals["Cat"] = 1] = "Cat";
  return Animals;
}(Animals || {});
Animals = /*#__PURE__*/function (Animals) {
  Animals[Animals["Dog"] = 2] = "Dog";
  return Animals;
}(Animals || {});
Animals = function (Animals) {
  Animals[Animals["CatDog"] = Animals.Cat - Dog] = "CatDog";
  return Animals;
}(Animals || {});

Expected:

var Animals = /*#__PURE__*/function (Animals) {
  Animals[Animals["Cat"] = 1] = "Cat";
  return Animals;
}(Animals || {});
Animals = /*#__PURE__*/function (Animals) {
  Animals[Animals["Dog"] = 2] = "Dog";
  return Animals;
}(Animals || {});
Animals = function (Animals) {
  Animals[Animals["CatDog"] = Animals.Cat - Animals.Dog] = "CatDog";
  return Animals;
}(Animals || {});

Note

The Dog should be qualified
