Svelte bind:group looses the dome element position when items are sorted

[mylastore]

When I sort class:selected={defaultImg === item.name} this can't figure out the actual element where the class needs to be assing to.

let defaultImg

 <Sortable {items} let:item={item} on:change={onChange}>
    <label class="label" class:selected={defaultImg === item.name} data-name='{item.name}'
           on:dblclick={e => handleRemoveFile(e)}>
      <input type='radio' name="defaultImg" bind:group={defaultImg} value='{item.name}'/>
      <img class="img-fluid" src='{item.thumb}' alt='{item.name}'>
    </label>
  </Sortable>
