flaky + pytest-asyncio: RuntimeError: Event loop is closed

Latest `pytest`, `pytest-asyncio` and `flaky` just can't live happily together.

When a flaky test fails, an error `RuntimeError: Event loop` is closed is reported instead of failure.
Edit: In fact, first test failure breaks the harness and "flaky" test is not retried.

Edit: cross-posted to https://github.com/pytest-dev/pytest-asyncio/issues/178

Start with the minimal reproducible example at https://github.com/dimaqq/mre-loop-closed and compare its behavior with the cross-posted pytest-asyncio issue. Reproduce the interaction among pytest, pytest-asyncio, and flaky; done means a failed flaky test is reported as a failure and retried instead of breaking with a closed event loop.
