Let's check where home:gladiac:mailman3 gets the python3-flufl.i18n-4.0-11.37
package from...

$ osc buildinfo home:gladiac:mailman3 python-mailman openSUSE_Tumbleweed x86_64
-M test | grep flufl.i18n
  <bdep name="python3-flufl.i18n" version="4.0" release="11.37" arch="noarch"
hdrmd5="b50ca82822cf8049924395a401435079" project="home:gladiac:mailman3"
repository="openSUSE_Tumbleweed"/>

Bingo! Check your home:gladiac:mailman3/python-flufl.i18n and you will see that
you disabled rebuilding the package yourself. pkgrel 11.37 is from April when
python3 was still python3.8
https://build.opensuse.org/package/binary/home:gladiac:mailman3/python-flufl.i18n/openSUSE_Tumbleweed/x86_64/python3-flufl.i18n-4.0-11.37.noarch.rpm

Even with multi-flavor in place before you disabled the build, you would have
had a python38-flufl.i18n sitting in your repo providing the required
python3-flufl.i18n.

So the correct bug title would have been "python-flufl.i18n needs to rebuild on
my home project", which is obviously not a valid bug for Tumbleweed.
