Describe the bug

the use of @mui/material/Hidden to toggle UI causes issues in test that need to be mocked (see #1795). Additionally Hidden has been deprecated. Mui docs recommend switching the JS implementation (which is used by jsonforms) to a ternary.

Expected behavior

Testing form contents should be possible

Steps to reproduce the issue

1. Create a form
2. Create a test (testing-library/react) around that form
3. Add an assertion on any form field
4. Call screen.debug() in the test
5. Note the jsonforms container is empty
