Hello, Can someone point me to docs that can help me understand how cancellation of subflows works? The behavior I'm seeing is that when I cancel a flow with sublfows, the subflows don't get cancelled as well, so I end up with a lot of ghost flows continuously running, because I thought they would have been cancelled. Also, most of my sublows don't have an option to cancel. They only have the option to copy or delete (from the UI). What causes that behavior to a flow?

Hi @Nicholas Torba! We've got a few PRs that are in process or have just been released that should help here: https://github.com/PrefectHQ/prefect/pull/9731 & https://github.com/PrefectHQ/prefect-ui-library/pull/1453 I think you're right to point out that we need to improve the docs on this. Thanks for the great prompt!
