[dmdin]

Your Environment

• Prettier version: 3.3.3
• node version: v20.12.0
• package manager: pnpm@10
• IDE: VScode

Describe the bug

Sorting imports is breaking on types in .svelte files

To Reproduce

• Svelte file with lang="ts"
• Type on exported variable

Expected behavior

Sorting works in Svelte files with lang="ts"

Screenshots, code sample, etc

This one breaks

<script lang="ts">
  export let name: string
</script>

And this one works

<script lang="ts">
  export let name
</script>
