+// Patch to allow custom element and shadow dom to work together, from:

Not sure what the best way is to put this in here...

It's required for the custom element polyfill to work with the shadow DOM
polyfill. But is not a part of either.

it seems reasonable, but maybe should have feature testing? in other words,
guard the createShadowRoot method with `if (originalCreateShadowRoot) {` ...

btw, this is a generated file right? Is there another commit I should review
that has this patch?

Done.

+var originalCreateShadowRoot = HTMLElement.prototype.createShadowRoot;
+HTMLElement.prototype.createShadowRoot = function() {
+  var root = originalCreateShadowRoot.call(this);
+  root.host = this;
+  return root;
+}

 })();
