Don't we want this code for windows when in ash?

+  aura::Window* active_window = ash::wm::GetActiveWindow();
+  if (!active_window)
+    return false;
+  ash::internal::RootWindowController* controller =
+      ash::internal::RootWindowController::ForWindow(active_window);
+  if (!controller)
+    return false;
+
+  return controller->GetFullscreenWindow();
+}
