743924 - Object.defineProperty replaces existing properties on the window object with undefined

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[Amjad Masad]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.151 Safari/535.19

Steps to reproduce:

window.FOO = {};
Object.defineProperty(window, 'FOO', {});
window.FOO;


Actual results:

Replaces FOO with undefined value.


Expected results:

Not alter FOO.

This will only happen on the *window* object. It doesn't happen on the self object of the worker.

Thanks for your report and sorry it took so long for someone to look at it.

This works for me in the current Nightly, executing this code in the console returns
> Object {  }

Is this still a problem?
