This PR seems to have caused a regression in test-utils types:
https://github.com/vuejs/ecosystem-ci/actions/runs/6822057901/job/18553448341#step:7:3107

@sodatea I'll have a look and fix the regression

The latest vuetify ecosystem-ci failure is also caused by this PR: https://github.com/vuejs/ecosystem-ci/actions/runs/6873130528/job/18696834234#step:7:1112

@sodatea Interesting I think their usage is incorrect 🤔

The error is because defineComponent({ ...{} as any }) cannot be used in conjunction with Component

declare function test(O: Component): void

test(
  // @ts-expect-error errors here
  defineComponent({
    ...({} as any)
  })
)

test(
  // works
  defineComponent({
    ...({} as Record<string, any>)
  })
)

const c =  defineComponent({
    ...({} as any)
  })
  
// works
test(c)

I suppose this happens because because typescript can't simply infer the correct type, IMO casting as any there is not very good, since it's telling the defineComponent it can be anything, like functions, symbol, number, etc...

Not sure if we should even support that tbh.
