Describe the bug

I am not exactly sure this is a bug of this plugin-in, sorry if this is not caused by this plugin-in.

Returning object of same name as standard object such as JSON or Date from setup function sometimes overrides standard object and sometimes not.

Although I cannot reproduce, I have an environment overriding always occur.

Reproduction

https://stackblitz.com/edit/vitejs-vite-4y7scdda?file=src%2Fcomponents%2FHelloWorld.vue

Steps to reproduce

1. Open the reproduction URL
2. Open src/components/HelloWorld.vue and look side by side with resulting page view. We see;
   • The first paragraph displays {{ JSON }}, and the JSON here is the object returned from setup function.
   • The second paragraph displays {{ JSON.toString() }}, and the JSON here is a standard object as can be seen from the resulting page shows [object JSON].

It's an edge case. BTW, using JSON as a variable name is bad
