I'm not sure: it looks like a configuration problem rather than a bug.

Your message said

dialog-1.3-13.20171209.el8.x86_64

which is a version of dialog almost 5 years old, on RHEL8
(and the version of Terminal.app is not mentioned).

fwiw, Fedora has newer versions:

https://src.fedoraproject.org/rpms/dialog

but since it doesn't look like any of the bugs that I recall,
it seems to be configuration.  If I had that firsthand, I'd
collect the output to the terminal using "script",

script -c 'dialog --title "This is title" --ok-label "OK" --msgbox "This is 
message" 20 40'

and examine the output e.g., using "unmap"
