> Object.getOwnPropertyDescriptor(document, 'documentElement')
< Object
configurable: false
enumerable: true
value: html
writable: false
__proto__: Object

This is a spec violation in a few ways but this bug is only about the configurable bit. It should only be false for [Unforgable].

As of today 
Object.getOwnPropertyDescriptor(document, 'documentElement')

returns 

undefined.
Comment 2 Oliver Hunt 2014-10-27 08:12:30 PDT 
documentElement (and the majority of dom attributes) are accessor members on the prototype chain.
Comment 3 Rajaram Gaunker 2014-10-27 08:44:33 PDT 
But the values are still not configurable.

Object
configurable: false
enumerable: true
get: undefined
set: undefined
__proto__: Object
