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?

Version

5.24.2

Current Behavior

Nested objects, arrays and arrays of objects in oneOf objects are not using default values set to them when changing to another oneOf object.

Expected Behavior

Default values should be applied to nested objects, arrays, arrays of objects when switching from one oneOf to another.

Steps To Reproduce

1. Open this react-jsonschema-form playground link
2. Change between different oneOf's (Test1, Test2, Test3)
3. Fields arr, runner and runners should be updating when changing between the oneOf's
