Describe your issue

Seems like prettier is unable to format code wrapped in expression blocks in Svelte / Kit. More specifically after doing some investigation - the {#await...} block.

I created an example repo with some expression blocks in the template to check.
Having an expression block like:

{#await promise()}
    <h1 class="text-2xl text-blue-600 animate-pulse font-bold">Loading...</h1>
{:then}
    <h1 class="text-blue-400 text-2xl font-bold">Loaded</h1>
{/await}

{#await promise() then}
    <h1 class="font-bold text-blue-400 text-2xl">Loaded without status</h1>
{/await}

and running pnpm format from the command line I would expect the classnames be formatted like:

{#await promise()}
    <h1 class="animate-pulse text-2xl font-bold text-blue-600">Loading...</h1>
{:then}
    <h1 class="text-2xl font-bold text-blue-400 ">Loaded</h1>
{/await}

{#await promise() then}
    <h1 class="text-2xl font-bold text-blue-400">Loaded without status</h1>
{/await}

Seems like classes in other blocks {#if}, {#each} are sorted correctly.
