I *think* we can make this private, at least, grepping doesn't show any usage
and a few local builds (including downstream) seemed to check out...

Done.

+        // If the container view is not focusable, we consider it always focused from
+        // Chromium's point of view.
+        if (!mContainerView.isFocusable()) return true;
         return mContainerView.hasFocus();
     }
