Bug 185130 – Inconsistency when try to access an property inside the "with" scope

• Component: JavaScriptCore
• Status: NEW

Hi, 
there's an inconsistence when we try to access an property inside the "with" scope.

OS: Ubuntu 16.04 x64
JavascriptCore (tag): 606.1.9.4

Step to reproduce:
```
var o = { f: "foo" };
with (o) {
  var desc = Object.getOwnPropertyDescriptor(this, "f");
  function f() {
    return "bar";
  }
  if (!(desc.value === undefined)) {
    throw new Error('expected: undefined, got: ' + desc.value);
  }
}
```
Actual results:
Error: expected: undefined, got: function f() {
  return "bar";
}

Expected results:
Pass without failures

V8 and Spidermonkey pass as expected, but Chakra and JavascriptCore returns the function f() inside "with" scope.
