Print Cancel Event not Firing

[smartin015]

Describe the bug

Adding a script / preprocessor to the Print Cancel events section of settings, then starting the queue and cancelling a print does not trigger the added script.

To Reproduce

See bug description.

Expected behavior

The script runs when the print is cancelled. Should confirm this works for G28 and @pause.

Additional context

Reported by folks from Protosthetics; they provided a sysinfo bundle offline, but the problem is reproducible in the dev environment.
