Description Erik Arvidsson 2011-09-14 13:50:45 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);

...

document.querySelector('x-foo').dispatchEvent(new Event('bar'))

throws TypeError: Illegal invocation

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