[BUG] wrapper breaks sometimes

[ParadiseFallen]

const factory = new LuaFactory();
    const engine = await factory.createEngine();

    const fun = (number : number) => {
      return number * 2;
    }
    const fn = await engine.doString(`
      return function (jsFunction)
        return function ()
          return funcction ()
            print(jsFunction(1))
          end
        end
      end
    `);

    fn(fun)()();

so sometimes pass functions just not don't works

error is

I ran the following in engine.test.js several times and did not find an issue:

    it('paradisefallen', async () => {
        const engine = await getEngine()

        const fun = (num) => {
            return num * 2
        }
        const fn = await engine.doString(`
          return function (jsFunction)
            return function ()
              return function ()
                print(jsFunction(1))
              end
            end
          end
        `)

        fn(fun)()()
    })

v.18.18.0 - Tested with latest build that has my fix to doString and with the previous release before that PR
