[mountSuspended] Easier access to setupState

[TimvdEijnden]

I'm testing a page. And inside the unit test I'd like to access the setup state, so I can execute the onSuccess function.
It is possible but it seems a bit cumbersome, I understand I have to find the component because it's wrapped.

<template>
  <div>Example</div>
</template>
<script setup type="ts">
const { data } = await useDetailData();

function onSuccess() {
  window.dispatchEvent(new CustomEvent('success'));
</script>

This a unit test, as you can see it's difficult to access the setupState of the wrapped Componened passed to mountSuspended.
Or is this already possible somehow? Else I'd be able to make a PR to expose the setupState for easier access.

it('should dispatch success event', async () => {
  const wrapper = await mountSuspended(DetailPage); // name of file is [...slug].vue

  const spy = vi.spyOn(window, 'dispatchEvent');
  // this works
  const detailPageWrapper = wrapper.findComponent({ name: '[...slug]'}).componentVM._.setupState;
 
  // But i'd prefer to use something like this instead: 
  const detailPageWrapper = wrapper.findComponent({ name: '[...slug]'}).vm
  // Or this
  wrapper.setupState.onSuccess();

  
  detailPageWrapper.onSuccess();

  expect(spy).toHaveBeenCalledWith(
    expect.objectContaining({ type: 'success' })
  );
});
