Steps to reproduce

interface Type {
  deep: {
    foo: any
  }
}

defineProps<{
  route: keyof Type['deep']
}>()

What is expected?

const __sfc__ = /*#__PURE__*/_defineComponent({
  __name: 'App',
  props: {
    route: { type: String, required: true }
  },

What is actually happening?

const __sfc__ = /*#__PURE__*/_defineComponent({
  __name: 'App',
  props: {
    route: { type: Object, required: true }
  },

Was broken in 3.4.24, since 3.4.27 works fine with the code below

defineProps<{
  route: keyof Type
}>()

but doesn't work with keyof Type['deep']

Why should it be String? Type['deep'] refers to an object: { foo: any }

Edit: sorry missed the keyof 🤦🏻‍♂️
