Using <script global> or `:global` selector doesn't silence eslint warnings

[dtzxporter]

Eslint will still complain about an 'unused' selector when svelte's linter knows that it's marked global.

<script global>
body { color: red; }
</script>

@dtzxporter what is your eslint confguration?

I assume this is meant to say <style global>? This isn't an official Svelte syntax, and is something added by svelte-preprocess. But, since that's an official library, I think it might make sense to automatically suppress warnings about the CSS in that case. :global() should already be working, because we're relying on the Svelte compiler itself for these warnings.
