Svetle 5 Version

[Lure5134]

For anyone interested, I have created a gist that you can copy into your project.
It is for svelte 5, uses runes andtypescript.
I have also tried to fix some bugs.

It can be used like this:

<VirtualList items={itemList} height="100%">
    {#snippet Children(data)}
        <Item data={data} />
    {/snippet}
</VirtualList>
