What is actually happening?

Comparing result: false

I know that the university uses a Proxy object to implement reactivity and to correct this situation, I need to use toRaw(). The problem is that it is not known whether Vue will be used or not outside Class.js.

This is expected and documented: https://v3.vuejs.org/guide/reactivity.html#proxy-vs-original-identity

I have recreated a simplified model and in fact, for comparison, an external library is used inside which Vue proxies objects.
