This only makes sense to me if documentA is undefined here. Is it?

Surprisingly it is not, I tried to addEventListener to it and that didn't throw
any exception.
I just double checked now trying to window.console.log(documentA) and it prints
[object HTMLDocumentElement].

+    window.console.log('both document are equal');
+  } else {
+    window.console.log('documents are different');
+  }
+  // At this point we have a new document where app's content would go
+  // (document.readyState == 'loading'), run watchForTag() once document's
+  // OnDOMContentLoaded fires.
+  document.addEventListener('DOMContentLoaded', function(e) {
+    window.console.log('shim: document.DOMContentLoaded');
+    watchForTag('WEBVIEW', function(addedNode) { new WebView(addedNode); });
+  });
 });
