Re: [w3c/webcomponents] HTMLElement.prototype.offsetParent leaks a node inside a shadow tree (#497)

It looks like Chrome returns `null` whenever the offset parent is inside a shadow tree.  I think a better change would be to return `null` if the offset parent is not an [unclosed node](http://w3c.github.io/webcomponents/spec/shadow/#dfn-unclosed-node) of the context object.
