Auto imports don't work in the script setup template without the options API

[isabolic]

Describe the bug

Auto imports don't work in the script setup template without the options API, I am guessing that this is because export default

Vue components are not registered inside auto-imports.d.ts without export default defineComponent({});

example is in here

CompA is registered while CompB is not

also sometimes you need to restart vite server after adding/removing export default defineComponent({});
