Description
Basically the title of the issue:

const formSchema = z.object({
    "orderby": z.boolean().default(true), // Set default value of `orderby` to `true`
});

const url = new URL("http://test.com") // create an `URL` with no `searchParams` set.

const form = await superValidate(url, zod(formSchema)) // URL validation.

console.log(form.data.orderby) // returns `false`
