"sudo: setrlimit(RLIMIT_CORE): Operation not permitted" error when using sudo in 20.04 LXD container

I fired up a LXD container using ubuntu-daily:f on my machine and every time I issue a comment inside the container using sudo, I get this error:

sudo: setrlimit(RLIMIT_CORE): Operation not permitted

I did some digging online and found this was reported against Fedora last fall which lead me to this bugzilla report:
https://bugzilla.redhat.com/show_bug.cgi?id=1773148

which seems to tie this to a change in sudo between 1.8.28 and 1.8.29.

Focal has 1.8.31:
bladernr@focal-builder:~/development/kernels-ubuntu/focal$ apt-cache policy sudo
sudo:
  Installed: 1.8.31-1ubuntu1
  Candidate: 1.8.31-1ubuntu1
  Version table:
 *** 1.8.31-1ubuntu1 500
        500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages
        100 /var/lib/dpkg/status

This is not an issue on Bionic:
bladernr@galactica:~/development/kernels-upstream/mainline$ apt-cache policy sudo
sudo:
  Installed: 1.8.21p2-3ubuntu1.2
  Candidate: 1.8.21p2-3ubuntu1.2
  Version table:
 *** 1.8.21p2-3ubuntu1.2 500
        500 http://archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages
        100 /var/lib/dpkg/status
     1.8.21p2-3ubuntu1 500
        500 http://archive.ubuntu.com/ubuntu bionic/main amd64 Packages

From the redhat bug, the described workaround does clear these messages up:

# set disable_coredump false

Once I've done that, the error messages go away.
