Svelte 5: $json returns undefined on initial load of the page

[TheRealSeber]

Describe the bug

<script lang="ts">
	import { _, json } from 'svelte-i18n';

	interface Feature {
		title: string;
		iconName: string;
		description: string;
	}

	const features: Feature[] = $json('landingpage.features') as Feature[];
       console.log(features)
</script>

{#each features as feature}
	<div class="relative px-6">
		<h1
			class="flex flex-col items-center text-center text-xl font-semibold leading-7 text-neutral-700"
		>
			<Svg name={feature.iconName} />
			{feature.title}
		</h1>
		<dd class="m-2 text-center text-lg leading-7 text-neutral-600">
			{feature.description}
		</dd>
	</div>
{/each}

Logs
Simply features is undefined

Expected behavior
Don't return undefined. YES landingpage.features json exists and $_ works as expected in other elements

Information about your project:
Svelte 5
svelte-i18n 4.0.1
Additional context
Wrapping the features around new rune $state didn't work. Also after redefining locale, the features are displayed as expected.

@kaisermann seems to be pretty critical
