Promise hangs when resolving a mocked instance

When a Promise wraps a mocked instance, it never resolves but hangs.

const { mock, instance } = require('ts-mockito')

const MockConnector = mock()
const connector = instance(MockConnector)

function connectorFactory() {
  return Promise.resolve(connector) // <== This mock instance (Proxy object) never get resolved by Promise.
}

(async () => {
  const created = await connectorFactory() // <== This Promise hangs forever.
  console.log('Connector created') // <== Never reached
})()

This issue is same with #155 which never gets noticed nor replied. A runnable sandbox: https://runkit.com/embed/5ljjgubxm9fm

For now, this is my workaround

JavaScript:

const {
  mock, // Don't use this
  instance,
} = require('ts-mockito')
const { Mocker } = require('ts-mockito/lib/Mock') // Must be below require('ts-mockito')

function betterMock(clazz) {
    const mocker = new Mocker(clazz)
    mocker['excludedPropertyNames'] = ['hasOwnProperty', 'then']
    return mocker.getMock()
}

TypeScript:

import {
  mock, // Don't use this
  instance
} from 'ts-mockito'
import { Mocker } from 'ts-mockito/lib/Mock' // Must be below import 'ts-mockito'

function betterMock<T>(clazz?: (new(...args: any[]) => T) | (Function & { prototype: T }) ): T {
    const mocker = new Mocker(clazz)
    mocker['excludedPropertyNames'] = ['hasOwnProperty', 'then']
    return mocker.getMock()
}

Useage example:

const {
  mock, // Don't use this
  instance,
} = require('ts-mockito')
const { Mocker } = require('ts-mockito/lib/Mock') // Must be below require('ts-mockito')

function betterMock(clazz) {
    const mocker = new Mocker(clazz)
    mocker['excludedPropertyNames'] = ['hasOwnProperty', 'then']
    return mocker.getMock()
}

const MockConnector = betterMock() // Instead of mock()
const connector = instance(MockConnector)

function connectorFactory() {
  return Promise.resolve(connector) // <== This mock instance can be resolved by Promise.
}

(async () => {
  const created = await connectorFactory() // <== This Promise resolves.
  console.log('Connector created') // <== Reached!
})()

@NagRock why this issue has not been addressed for such a long time?
