Describe the bug

I'm following the instructions on https://github.com/plotly/dash/blob/dev/CONTRIBUTING.md, and runningpytest tests/integration/devtools/test_devtools_error_handling.py on Python 3.11, and the test fails due to missing traceback:

I tested it on Python 3.10 and it worked fine.

Expected behavior

The test should pass on Python 3.11 too.

It appears dash works mostly fine on Python 3.11, but it's not officially declared? Plus this test fails.

Regarding the failure, maybe this comment is relevant? https://github.com/pallets/werkzeug/pull/2640#issuecomment-1503454090:

It's actually not sufficient right now for Python 3.11's new traceback features.

Start by running pytest tests/integration/devtools/test_devtools_error_handling.py under Python 3.11 and compare its traceback output with Python 3.10. Inspect the failing test and the referenced Werkzeug traceback behavior; done means the test passes on Python 3.11 while preserving the expected error details.
