If i refer to "document" here (in file's global scope), this would be document
A.
i.e.
var documentA = document;

-window.addEventListener('DOMContentLoaded', function() {
-  watchForTag('WEBVIEW', function(addedNode) { new WebView(addedNode); });
+renderViewObserverNatives.OnDocumentCreatedForCurrentContext(function() {
+  // 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) {

(See this after next comment)
this "document" is documentB.

+    watchForTag('WEBVIEW', function(addedNode) { new WebView(addedNode); });
+  });
 });

Let's say I have an app

background.js:
..onLaunched.addListener(function() { chrome.app.window.create('main.html'); });

main.html:
<script src="main.js"></script>

main.js:
var documentB = document; // <-- this
