            Bug ID: 164335
           Summary: Getter for Object.prototype which returns this ends up
                    returning undefined
    Classification: Unclassified
           Product: WebKit
           Version: Safari 10
          Hardware: Unspecified
                OS: macOS 10.12
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: fernandesdacostalucas at gmail.com

When adding a property to the `Object.prototype` that returns `this` when it's accessed, `undefined` gets returned.

You can check this by running the following code at `Safari`:

```js

Object.defineProperty(Object.prototype, 'bla', {
  get: function() {
    return this;
  }
});

var anObj = {example: 'foo'};

console.log(anObj.bla);
```

The expected behavior should be to return the object on which we're accessing the property.

PS: You guys at Apple rock, thank you very much for the hard work!
