Steps to reproduce:

Suppose you're about to try to implement shims or polyfills for the CSSStyleDeclaration class. You add a getter and a setter to CSSStyleDeclaration.prototype.


Actual results:

You suddenly face a very annoying problem: it's impossible, given a style object, to get a reference back to the element/pseudo-element it refers to.


Expected results:

A first milestone towards fixing this problem involves implementing the CSSPseudoElement interface from the CSS PSeudo-Elements Module (http://dev.w3.org/csswg/css-pseudo/#CSSPseudoElement-interface).

Then, a proporty could be added to CSSStyleDeclaration named "parentElement" returning a DOM-equivalent of the value that is already available to the browser itself.
