A `hydratable` value with key `%key%` was created, but at least part of it was not used during the render.
The `hydratable` was initialized in:
%stack%
The most likely cause of this is creating a hydratable in the script block of your component and then awaiting
the result inside a svelte:boundary with a pending snippet:
<script>
import { hydratable } from 'svelte';
import { getUser } from '$lib/get-user.js';
const user = hydratable('user', getUser);
</script>
<svelte:boundary>
<h1>{(await user).name}</h1>
{#snippet pending()}
<div>Loading...</div>
{/snippet}
</svelte:boundary>
Consider inlining the hydratable call inside the boundary so that it's not called on the server.
Note that this can also happen when a hydratable contains multiple promises and some but not all of them have been used.
