Description

Using Zod on <UForm>
When using z.refine() and passing a path parameter, the path is parsed incorrectly.
Possibly from: form.ts#45

Example Schema:

const schema = z
  .object({
    email: z
      .union([
        z.string().email(),
        z.literal(""),
      ])
    phone: z
      .union([
        z.string(),
        z.literal(""),
      ])
  })
  .refine(({ phone, email }) => phone?.length || email?.length, {
    message: "Please provide either an email or a phone number",
    path: ["phone", "email"],
  });

The resulting error from the From element shows name as "phone.email":

  {
    _custom: {
      type: "reactive",
      stateTypeName: "Reactive",
      value: {
        name: "phone.email",
        id: "__vue_devtool_undefined__",
      },
    },
  },
];

The zod error result is: ["phone", "email"]

{
  code: "custom",
  path: ["phone", "email"],
};

Workaround:
I can pass one path at a time, by using ["phone"] but I cannot pass multiple paths.
