[StorageFactory] Unable to use Object.keys|entries|values(sessionStorage) after #1385

[motss]

Describe the bug
We can actually get all the keys of a Storage using Object.<keys|entries|values>() (Also see here). After #1385, it no longer works and we will seethe following error:

TypeError: 'getOwnPropertyDescriptor' on proxy: trap reported non-configurability for property '<key>' which is either non-existent or configurable in the proxy target

To Reproduce
Simple go to https://stackblitz.com/edit/vitest-dev-vitest-9lccsx and you will see the error in the terminal.

Also a simple code snippet to reproduce the error:

import { expect, it } from 'vitest';

it('Object.keys on window.sessionStorage', () => {
  window.sessionStorage.setItem('a', '1');

  expect(Object.keys(window.sessionStorage)).toEqual(['a']); // TypeError
  expect(Object.values(window.sessionStorage)).toEqual(['1']); // TypeError
  expect(Object.entries(window.sessionStorage)).toEqual([['a','1']]); // TypeError
});

Expected behavior
Object.keys(widow.sessionStorage) should return a list of keys in the sessionStorage
