Do you want to use isInTreeScope() or inDocument()?

I am not familiar to how the shadow dom is used so I decided to log its
modifications as well. But, probably should have used inDocument().

I'll change it to inDocument()

+        if (activityLogger) {
+            Vector<String> argv;
+            argv.append("a");
+            argv.append(fastGetAttribute(hrefAttr));
+            activityLogger->logEvent("blinkAddElement", 2, argv.data());

[haraken, 2014/06/23 15:49:42]

2 => argv.length()

Done.
