Code was written in 2014, only upstreaming happened in 2015. In general, we do
not change the copyright notice when upstreaming (moving from private repo to

The code file is located at
"components/dom_distiller/core/javascript/domdistiller.js", so this is
consitent.

+  try {
+    // UIWebView's JavaScript engine has a bug that causes crashes when creating
+    // a separate window object (as in the non-iOS version of this file), so
+    // allow the script to run directly in the window until a better solution
+    // is created.
+    // TODO(kkhorimoto): investigate whether this is necessary for WKWebView.
+    <include
+    src="../../../../third_party/dom_distiller_js/package/js/domdistiller.js"/>
+    // UIWebView requires javascript to return a single string value.
+    return JSON.stringify(

+    if (e.stack != undefined) window.console.error(e.stack);
