Comment (by nicolefurlan):

 == Test Report
 This report validates that the indicated patch addresses the issue.

 Patch tested: https://github.com/WordPress/wordpress-develop/pull/4035

 === Environment
 - OS: macOS Ventura 13.4.1
 - PHP: 8.2.11
 - WordPress: trunk

 === Actual Results
 - ✅ Issue resolved with patch.
 - ✅ Unit tests pass.

 === Additional Notes
 - I used WP CLI via `npm run env:cli` to test this and verified that when
 executing `unregister_setting( 'somethingrandom', 'somethingrandom' );` on
 the CLI, the `Notice: Trying to access array offset on value of type null
 in /var/www/src/wp-includes/option.php on line 2821` notice appears
 without the patch, and disappears after applying the patch.
 - I ran phpunit on `registration.php` via `npm run test:php --debug
 tests/phpunit/tests/option/registration.php` and verified that all unit
 tests pass in `registration.php`.
