Question about restoreScrollState.

[nrikiji]

I have embedded the following page as a child element of Router.

The scroll position is not restored on browser back. Is this because the height of the element is not enough when restoring?
Also, I would like to know if there is a way to work around this.

let items = []

onMount(() => {
  // Call web api and set it to items every time
})

<div>
  {#each items as item}
    <div on:click={()=>push("/detail/" + item.id)}>・・・</div>
  {/each}
</div>
