(Why are you reporting problems on an Ubuntu system on a debian.org
mailing list?)

I cannot reproduce this.  I tried bash 4.4 on Debian 10 (self-built),
the standard bash 4.4 package (version 4.4-5) on Debian 9, and the standard
bash 5.0 package (version 5.0-4) on Debian 10.

You might want to try running a new instance of bash with --norc --noprofile
to remove any dot file settings from the picture.
