I'm not sure why this was added initially, but it makes more sense to me that
the setting should be applied globally

-  // theming.
-  if (window->type() == ui::wm::WINDOW_TYPE_NORMAL ||
-      window->type() == ui::wm::WINDOW_TYPE_POPUP) {
+  if (window) {
     profile = reinterpret_cast<Profile*>(
         window->GetNativeWindowProperty(Profile::kProfileKey));
   }
