Constructor execute fail in the js-interpreter

[CommanderXL]

The example code is:

const p = new Interpreter('')

function Aa(handler) {
  this.handler = handler
}

function AdWrapper () {
  return Aa
}

var str = 'console.log(111, new (AdWrapper())(function() {}))'    // Throw Error:  Cannot set property 'handler' of undefined

p.setProperty.(p.globalObject, 'AdWrapper', p.createHostProxy(AdWrapper, true))
p.appendCode(str)
p.keepRun()

Well, If I run the code in the normal js environment, it ok:

function Aa(handler) {
  this.handler = handler
}

function AdWrapper () {
  return Aa
}

console.log(111, new (AdWrapper())(function() {}))   // it's ok
