Body content is not generating with s.mdx().optional()

[dgknca]

If you use s.mdx().optional() instead of s.mdx(), the body is never generated.

Yes, this is a known issue because transform inside s.mdx() does not work when it is modified as optional.

This is related to the internal design of upstream zod, e.g.

z.string().transform(() => {
  // not execute if input undefined
}).optional() // => ZodOptional

z.string().optional().transform(() => {
  // always execute
}) // => ZodEffect

I will try to solve this issue when I have time.
