ctrl+c does not terminate all par-each instances

How do I terminate all the commands running with par-each? When I press ctrl+c, it seems that nushell only sends the signal to one of the tasks, rather than all of them.

Steps To Reproduce

With Python installed, run ..3 | par-each { python -c "import time, itertools; [(print(i), time.sleep(0.1)) for i in itertools.count()]" } and press ctrl+c. On Windows, all Python instances are terminated (as expected), but on Linux it seems like only 1 is terminated.

This is also the case for each right?

Since the test case can only be terminated by repeated ctrl+c.

..3 | each { python -c "import time, itertools; [(print(i), time.sleep(0.1)) for i in itertools.count()]" }
