[xiaodong2008]

Test Case:

test('in component event handler via emit (async)', async () => {
  const err = new Error('foo')
  const fn = vi.fn()
  const Comp = {
    setup() {
      onErrorCaptured((err, instance, info) => {
        fn(err, info)
        return false
      })
      return createComponent(Child, {
        async onFoo() {
          throw err
        },
      })
    },
  }
  const Child = {
    props: ['onFoo'],
    setup(props: any, { emit }: any) {
      emit('foo')
    },
  }
  define(Comp).render()
  await nextTick()
  expect(fn).toHaveBeenCalledWith(err, 'setup function')
})
