Inline typescript types in svelte markup break prettier autoformatting

[hmprt]

As title says. The following markup breaks prettier on the file:

{#each keys as key}
	{@const setting = device.settings[tab][key] as ConfigurableSetting}
	<SetConfig {setting} {key} />
{/each}

but this markup does:

{#each keys as key}
	{@const setting = device.settings[tab][key]}
	<SetConfig {setting} {key} />
{/each}
