To Reproduce

// src/routes/index.svelte
<script lang="ts">
    import dayjs from "dayjs";

    const time = dayjs();
</script>

Expected behavior
the default import should work as expected

Severity
medium, i could use a different date library but i found this one is a really small and nice one

Additional context
I don't know if this issue is svelte kit related vite related.
I also turned on "allowSyntheticDefaultImports": true in tsconfig.json

See #699.
