There is a pre-existing bug where cancellation requests are ignored for alerted asyncs (i.e. async instances that are not actually completed and can go back from the "terminated" state to the pending state).  Perhaps it's worth addressing that bug first?  https://www.winehq.org/pipermail/wine-devel/2022-March/210053.html
