JSDoc hints are lost after using `.extend`

[todor-a]

Once you use .extend, any JSDoc hints are lost.

import { z } from 'zod';

const v1 = z.object({
    /** this works */
    userId: z.string(),
});

const v2 = z.object({
    /** this doesn't */
    itemId: z.string(),
}).extend(v1.shape);

const instance1: z.infer<typeof v1> = {
    userId: '2' // has hint on hover
}

const instance2: z.infer<typeof v2> = {
    itemId: '1',
    userId: '2'
}

In my experiments, this isn't a solvable problem, but perhaps others can succeed where I've failed.

This works in 3.22.4

Merged and landed in v3.23.7
