What's the purpose of the patch?

I see the patch file to add NS_VUE_APP to the global, but it doesn't seem to be used anywhere in the project as the comment suggest.

ns-vue-vite-demo/patches/nativescript-vue+3.0.1.patch

Lines 9 to 12 in b9bdc6c

	+ // Patch: expose app instance globally for HMR access
	+ // This primarily allows back navigation to be restored
	+ // when doing HMR within deep navigation stacks
	+ globalThis.__NS_VUE_APP__ = app;
