Bug: spying on wrapper.vm for script setup methods using Vue 3.2.45 and VTU 2.2.2 stop working

[felixzapata]

Describe the bug

All the tests we have using explicit casting for wrapper.vm in order to spy methods stop working after updating to Vue 3.2.45 and VTU 2.2.2.

Related bugs:

• Feature request: Testing Vue3 computed properties with TypeScript SFC #1791
• Better types for wrapper.vm when the component is closed #972

To Reproduce

This is the minimal sample based on one of the failing tests. With the previous version, this test passes.

Expected behavior

The test must be passed.

👍 Thanks for the repro

This should be fixed by #1860

Vue changed its internal, and we now have to do a bit more work in VTU to allow the same feature than previously. You can stay on Vue v3.2.44 until this is released
