nit: Let's use a different word than "extension," which has a more concrete
meaning in Chrome.

Done.

+// Android WebView.
+class NavigationControllerWebView {
+ public:
+  // Loads a 'data:' scheme URL with specified base URL and a history entry URL.
+  // This is only safe to be used for browser-initiated data: URL navigations,
+  // since it shows arbitrary content as if it comes from |history_url|.

Is there any clean way to point to the Android WebView documentation here, or at
least make a reference to it?  I found the API description there helpful for
understanding why this is needed.

I've added a reference to the class-level comment.
