omitExtraData incorrectly removes enum objects

[filbertteo]

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

core

Version

v6.0.0-beta.18

Current Behavior

With the omitExtraData prop set to true, RJSF removes enum objects from the form data. This will also cause validation to fail for required fields.

Expected Behavior

With the omitExtraData prop set to true, RJSF does not remove enum objects from the form data.

Steps To Reproduce

1. Visit the playground link
2. Click the submit button
3. Notice that validation fails even though the location field has a value.
4. Update the JSON schema to remove the required fields. Click the submit button.
5. Notice that the form successfully submits.
   1. However, if you check the submitted formData in the console log, the location field is missing.
   2. Also notice that the location field in the form is now empty after the form is submitted.

Environment

N/A

@filbertteo It works fine for non-object-based enums. This example is related to the enum having an value that is an object. I've fixed the code to also handle that.
