It is a bug introduced with the latest update of the gnome-shell.
The issue has been fixed upstream.
F40 might receive it as an update sometime in the future. F41 doesn’t have this issue, as with GNOME 47 they’ve changed the layout of these confirm buttons.
See also this thread[1] discussing the issue (with some other threads merged into it).
