		// Even if the {@html } block seems static, it should be preserved as such, because it could be dynamic originally
		// (like {@html browser ? 'foo' : 'bar'} which is then different between client and server.
		// Also see https://github.com/sveltejs/svelte/issues/8683 where this happened for Svelte 4.
