Reproduction Steps

Create vue component using the composition API:

<script setup lang="ts">

</script>
<template>

</template>

I can't reproduce this on the same commit:

Do you have any custom languages.toml config?

Yeh that's it - I had a typescript language config that set

injection-regex = "typescript"

removing that from my config resolves the problem.
