Describe the bug

const wrapper = await mountSuspended(OptionAPIComponent)

wrapper.vm.$data is empty wrapper.setData({...data}) will result into error:

TypeError: Cannot add property, object is not extensible

Furthermore, I cannot call any method of the component instance:

TypeError: wrapper.vm.myMethod is not a function

Additional context

Component written in composition api doesn't have this issue. @vue/test-utils doesn't have this issue.
