Should this be a TODO?

Done.

+// either do not need |root_window| or can access to ash which could access root
+// window directly by calling ::ash::wm::GetRootWindowAt. Consider remove
+// |root_window| once we have a way to get root window from |screen_point| on
+// Android.

     const gfx::Point& screen_point,
-    const std::set<gfx::NativeWindow>& ignore);
+    const std::set<gfx::NativeWindow>& ignore,
+    gfx::NativeWindow root_window);
