1365840 - location has a toJSON member and its value is undefined

Status: RESOLVED DUPLICATE of bug 1333045

(Core :: DOM: Core & HTML, defect)

Description

[PhistucK]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.96 Safari/537.36

Steps to reproduce:

I typed in the console -
> 'toJSON' in document.location
true
> Object.getOwnPropertyDescriptor(document.location, 'toJSON')
Object { value: undefined, writable: false, enumerable: true, configurable: false }


Actual results:

document.location has a toJSON member and its value is undefined.


Expected results:

Looks like document.location should not have a toJSON method/member.

Chrome does not have such a member.

This was reproduced using Firefox 53.0.2.

The issue is no longer on Firefox nightly 55. Looks it's a dup. of bug 1333045.
