[issue45390] asyncio.Task doesn't propagate CancelledError() exception correctly.

Andrew Svetlov added the comment: 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

[issue45098] asyncio.CancelledError should contain more information on cancellations

Andrew Svetlov added the comment: After TaskGroup merging, the second `cancel()` call returns `False` and doesn't initiate the actual cancellation if it was scheduled by the first `cancel()` call. I believe it "fixes" async-timeout: the first canceller wins. --
