It seems that onMounted is being called in the main view before the application is available.

If I do it, it fails because onMounted is called before rootApp is defined in ns-vue, tracing the code it seems that the rootApp has not yet been defined here https://github.com/nativescript-vue/nativescript-vue/blob/main/src/index.ts#L92
