Objects behave differently from the expected behavior

[wvad]

const { VM } = require('vm2');
const { deepStrictEqual } = require('node:assert');

const vmFunc = new VM().run(`obj => {
  obj = Object.create(obj);
  obj.aa = 1;
  return Reflect.getOwnPropertyDescriptor(obj, 'aa')?.value;
}`);

const obj01 = { aa: 0 };
const res01 = vmFunc(obj01);

const func = obj => {
  obj = Object.create(obj);
  obj.aa = 1;
  return Reflect.getOwnPropertyDescriptor(obj, 'aa')?.value;
};

const obj02 = { aa: 0 };
const res02 = func(obj02);

deepStrictEqual([obj01.aa, res01], [obj02.aa, res02]);

AssertionError [ERR_ASSERTION] [ERR_ASSERTION]: Expected values to be strictly deep-equal:
+ actual - expected

  [
+   1,
+   undefined
-   0,
-   1
  ]

This are known issues.

I think you should add to known issues that if Object.create is used with a proxied object as the first argument, it won't work as expected. https://github.com/patriksimek/vm2/issues/471#issue-1376790466
