> 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.
Oliver Hunt
documentElement (and the majority of dom attributes) are accessor members on the prototype chain.

But the values are still not configurable.
Object
configurable: false
enumerable: true
get: undefined
set: undefined
__proto__: Object
