SSR doesn't seem to work with conditional rendering with Store

Question

/lib/store/store.js

import { writable } from 'svelte/store'

export const store = writable({ show: true )) 

/route/index.svelte

<script>
import { store } from '$lib/stores/store'
</script>

{#if $store.show}
  <div class="view">
   My conditional elements
  </div>
{/if}

SSR stops working with conditional rendering with store. Is this a supposed behavior? Or am I doing something wrong?
