Doing a mate-terminal --command top with the same steps doesn't show the confirmation dialogue and produces that warning. But if I have a mate-terminal window open and then do the same steps on xterm, there's no warning (and no confirmation either).

Basically, if there's any running process in the terminal that needs closing first (like a manpage or top) there should be a confirmation dialogue upon closing mate-terminal window, but there isn't any.

The issue doesn't show if I use mate-terminal instead of xterm.

This is with 1.24.0 for both MATE and mate-terminal on Fedora 32.

Looks like using --command top and thus top opening in a new terminal, the child terminal is not recognizing that it has an ongoing process and can thus be closed without the confirmation dialog. True here whether running this command (and spawning the child mate-terminal) from mate-terminal or xterm

[lukefromdc]

Confirming, though this should be edited to reflect that the issue is in a terminal opened from --command
