Svelte 5: Bug - ReferenceError occurs when defining a snippet inside a script along with bind:value in SSR mode.

[mariansimecek]

Describe the bug

Can't define a snippet and bind a value at the same time. This leads to the error: ReferenceError: snippet is not defined. This only happens in SvelteKit with SSR mode on, when I disable it, everything works fine.

<!-- +page.svelte -->
<script>
	import TextInput from './TextInput.svelte';

	let value = $state('');
	const _snippet = snippet;
</script>

{#snippet snippet()}
	Something
{/snippet}

<TextInput bind:value />
value: {value}

<!-- TextInput.svelte -->
<script>
	let { value = $bindable() } = $props();
</script>

<input type="text" bind:value />

Probably related to #11010

I'm unable to see any issues here locally or when I move it to the REPL. Going to assume it's been fixed since.
