We did two tests today. First was an upgrade of the complete system from Buster 
to Testing. This worked. mariadb-server and mariadb-client worked both after
upgrade.
Then we tried with apt pinning mariadb-server to testing, and the rest of the 
system to bullseye with the following settings:

root at test:/etc/apt/preferences.d# apt-cache policy mariadb-server
mariadb-server:
  Installed: (none)
  Candidate: 1:10.5.12-1
  Version table:
     1:10.5.12-1 1000
          1 http://ftp.de.debian.org/debian testing/main amd64 Packages
     1:10.5.11-1 500
        500 http://deb.debian.org/debian bullseye/main amd64 Packages
     1:10.3.29-0+deb10u1 500
        500 http://mirror.hetzner.de/debian/packages buster/main amd64 Packages
     1:10.3.25-0+deb10u1 500
        500 http://mirror.hetzner.de/debian/security buster/updates/main amd64 Packages

This output was after upgrade, that is why it says "Installed: (none)"
After this test, mariadb-server and client where again missing.

Extract of /var/log/apt/history.log:
