However, it does not check what exact events are emitted after block-job-cancel is executed. More importantly, it does not use throttling to ensure that it covers the case of block-job-cancel before READY. It would be possible to add this case to 041, but considering it is already our largest test file, it makes sense to create a new file for these cases.
