I have a pull request for the issue.
It doesn't use `Future.set_exception()` but creates a new CancelledError() with propagated message.
The result is the same, except raised exceptions are not comparable by `is` check.
As a benefit, `_cancelled_exc` works with the patch, exc.__context__ is correctly set.

The patch is not backported because it changes existing behavior a little. I'd like to avoid a situation when third-party code works with Python 3.11+, 3.10.3+, and 3.9.11+ only.
