Describe the bug

With vitejs v2.0.0-beta.50
We can use await in a top level

<script setup>
import { query } from '~core/Query'
const { data } = await query(`{}`)
</script>

I try to update to vitejs v2.0.0-beta.70 and i got this error error: Top-level await is currently not supported when bundling

In the script setup rfc doc the await top level is allowed

I'm missing something ?
