New operator not wholly supported

[rossm6]

This does not work -

const p = parse("new Date(new Date().setDate(new Date().getDate()-5))");
evaluate(p, { Date }); // gives error: Error: 'setDate' is not a function

P.S. I have the "new" keyword plugin added (which is why it gets passed)

I checked the generated AST by jsep and confirmed the issue:

  "type": "NewExpression",
  "arguments": [
    {
      "type": "CallExpression", // not NewExpression
      "arguments": [
        {

              "type": "MemberExpression",
              "computed": false,
