Steps to reproduce

I have two question:

1. I can't get expose data hint when use typescript

const handleNameChange = () => {
  count.value = Math.random();
  console.log(TestComponentRef.value?.title); // can't get expose data hint
};

2. I must to write:

<script lang="ts">
export default {};
</script>

if not add that, when import TestComponent from "./components/TestComponent.vue", will get error: '... not export the default' error

What is expected?

Get the right hint.

What is actually happening?

Get error.
