Combobox autocomplete breaks in Svelte 5.

[memestageceo]

Describe the bug

Shadcn-svelte Combobox works in Svelte 4, but doesn't in Svelte 5. Tried with both, the code is same in both, the only different is svelte version.

I've created a repo for the same. The svelte 4 works well, svelte 5 fails - keeps adding new items when trying to filter lists

Reproduction

Here's a repo. The svelte 4 version works. Svelte 5 fails - with both svelte 4 and svelte 5 syntax.

This seems to be happening directly on the dependency used for the combobox cmdk-sv
from this link: huntabyte/cmdk-sv#92
you can find a workaround:

<script>
let search = $state('')
</script>

<Command.Root>
  <Command.Input placeholder="Search framework..." bind:value={search} />
  {#key search}
    <Command.Group>
      {#each frameworks as framework}
        <Command.Item>
        ...
        </Command.Item>
      {/each}
    </Command.Group>
  {/key}
</Command.Root>

We're not addressing Svelte 5 issues until it is out of RC. We cannot control things that Svelte 5 breaks unfortunately.
