Pytest-rerunfailures==16.0 causes INTERNALERROR with XFAIL tests

The pytest-rerunfailures 16.0 causes INTERNALERROR with XFAIL tests (at least in some cases) with "worker_internal_error" of pytest-xdist After pytest-rerunfailures 16.0 has been releasesd, our tests started to crash on XFAIL tests in Airflow CI. This is entirely reproducible with our CI image, and the error goes away after we downgrade to pytest-rerunfailures 15.1 Example failure here https://github.com/apache/airflow/actions/runs/17316803449/job/49161143268?pr=54913#step:4:231 -> I also copied the error below. ## How to reproduce it 1) check-out Airflow be91b42d9044930c991979ffffd69d4e9174d975 commit 2) Install breeze: `uv tool install -e ./dev/breeze` 3) Run`breeze ci-image build --upgrade-to-newer-dependencies` (it will build docker container and pull latest pytest-rerunfailures 4) Run `brreze` - you will be inside the container 5) cd shared/secrets_masker 6) run `pytest --color=yes -n auto` -> crash 7) run `uv pip install pytest-rerunfailures==15.1` -> only pytest-rerunfaiures is downgraded 8) run `pytest --color=yes -n auto` -> NO crash Error output below: ``` INTERNALERROR> def worker_internal_error( INTERNALERROR> self, node: WorkerController, formatted_error: str INTERNALERROR> ) -> None: INTERNALERROR> """ INTERNALERROR> pytest_internalerror() was called on the worker.
