node-addon-api: Napi::TypeError::New is not an instanceof TypeError

Consider:

Napi::Value Rwar(const Napi::CallbackInfo& info) {
  Napi::Env env = info.Env();
  Napi::TypeError::New(env, "Wrong number of arguments")
      .ThrowAsJavaScriptException();
  return env.Null();
}

test('throws wrong number of arguments', () => {
  expect.assertions(1)
  try {
    addon.rwar()
  } catch (err) {
    expect(err).toBeInstanceOf(TypeError)
  }
})

For whatever reason I am getting:

● throws wrong number of arguments

    expect(received).toBeInstanceOf(expected)

    Expected constructor: TypeError
    Received constructor: TypeError

       6 |     addon.rwar()
       7 |   } catch (err) {
    >  8 |     expect(err).toBeInstanceOf(TypeError)
         |                 ^
       9 |   }
      10 | })
      11 | 

Whenever I check err instanceof Error or err instanceof TypeError both return false. Is there something I am doing wrong, or is this a bug?
