Eslint not running in script tags

[tylermcrobert]

Describe the bug

When looking at the following:

<script lang="ts">
	import { onMount } from 'svelte';

	function sayHi() {
		console.log('hi');
	}
</script>

I should be seeing Eslint errors that complain about no-unused-vars. I've also configured my eslint with the no-console rule that should also be triggered. Removing lang="ts" does not fix the issue

Reproduction

REPL here

Note, I'm not sure if REPL will show any eslint errors at all, you may have to download it.

Not entirely sure, but I think this should be in the language-tools repo.
