Svelte 5: <svelte:self /> can't be directly added to a {#snippet}

[robertadamsonsmith]

Describe the bug

Adding <svelte:self /> directly to a {#snippet}, raises the error:

<svelte:self> components can only exist inside {#if} blocks, {#each} blocks, or slots passed to components

I would have expected it to be allowed though. Adding an {#if true} block to the snippet effectively silences the error, allowing the expected behaviour.
