I think This is not a bug but I understood your issue.

Always both italic and bold 's svelte:fragment is rendered in your REPL.
Therefore $$slots.someName should be always true.

I think it's convenient If the below statement is supported.
But now it is not supported.

<H2>
  {#if italic}
    <svelte:fragment slot="italic">
      italic
    </svelte:fragment>
  {/if}
</H2>
