kit: [hooks] `sequence` helper function doesn't account for `preload`

Describe the bug

The sequence helper funciton doesn’t seem to call the preload function specified in handle hooks.

Reproduction

Reproduction on StackBlitz

Please find the hooks.server.js file as such:

import { sequence } from '@sveltejs/kit/hooks';

const preloadFonts = async ({ event, resolve }) =>
	await resolve(event, {
		preload: ({ type, path }) => {
			if (type === 'font') {
				console.log(type, path);
				return true;
			}
			return false;
		}
	});

export const handle = sequence(preloadFonts);

// export const handle = preloadFonts;

Run npm run build.

The following log output is seen when handle is set to preloadFonts, but not when it is set to sequence(preloadFonts).
