Status: RESOLVED DUPLICATE of bug 1371936

(DevTools :: Console, defect)

Description

[kevinjjackson93]

What did you do?
================
1. Log an object with three keys as integers. (e.g.   console.log({1: '1', 2: '2', 3: '3'});
2. Open the developer tools to inspect the object.
3. Select the logged Object to expand the key & values.

What happened?
==============
The first key/value pair in the object gets removed from the view.

What should have happened?
==========================
The first key/value pair should be displayed.

Is there anything else we should know?
======================================
