Describe the bug

Hi! There seems to be an issue when using mountSuspended on a component with defineOptions({ inheritAttrs: false }) where attributes bound using v-bind="$attrs" are missing.

For instance with this component:

<template>
  <div>
    <button v-bind="$attrs"> <slot /> </button>
  </div>
</template>

<script setup lang="ts">
defineOptions({ inheritAttrs: false })
</script>

The first test below using mountSuspended will fail because the attribute is missing, whereas the test using mount from @vue/test-utils works as expected.

import { test, expect } from 'vitest'
import { mount } from '@vue/test-utils'
import { mountSuspended } from '@nuxt/test-utils/runtime'
import ExampleComponent from '~/app/components/ExampleComponent.vue'

test('with mountSuspended', async () => {
  const wrapper = await mountSuspended(ExampleComponent, { attrs: { 'aria-label': 'Aria Label' } })
  expect(wrapper.find('[aria-label="Aria Label"]').exists()).toBe(true)
})


test('with mount', () => {
  const wrapper = mount(ExampleComponent, { attrs: { 'aria-label': 'Aria Label' } })
  expect(wrapper.find('[aria-label="Aria Label"]').exists()).toBe(true)
})
