Description Erik Arvidsson 2011-09-14 12:12:55 PDT 
This depends on some of the component model patches.

function Foo() {
  HTMLElement.call(this);
}
Foo.prototype = Object.create(HTMLElement.prototype);
HTMLElement.register('x-foo', Foo);

getComputedStyle(new Foo)  // null, expected CSSStyleDeclaration

The prototype that exhibited this bug is an evolutionary dead-end, so ditching this bug.
