 * We assume that NavigationEnd is the final page resolution and call GA `page_view` command.
 *
 * To avoid double binds, we also destroy the subscription when de Bootstrap Component is destroyed. But, we don't know for sure
 * that this strategy does not cause double bind on multiple bootstrap components.
 *
 * We are using the component's injector reference to resolve Router, so I hope there is no problem with double binding.
 *
 * If you have this problem, I encourage not Use NgxGoogleAnalyticsRouterModule and attach the listener on AppComponent initialization.
