Highest integration tests have"risky" warning in AttributesTest: Test code or tested code did not remove its own exception handlers

[weitzman]

Based on https://github.com/laravel/framework/issues/50951#issuecomment-2923415400, I put a breakpoint into \PHPUnit\Framework\TestCase::restoreGlobalErrorExceptionHandlers and see that _drupal_exception_handler is causing this message.
