(Ahhh. The bugreport said it was testing/sid system, so I thought you
were on it for a while already, not just upgraded from stable…)

So upgrading mariadb will bring you galera-4 which conflicts with
galera-3. Package removals are not allowed in 'upgrade' so this mariadb
upgrade will be reverted and you will get it in the next step with
a full-upgrade – which will remove galera-3.
So, yeah, apt could potentially figure out that it could upgrade
galera-3 in this setup as it can't do the mariadb upgrade, but in
practice this will just waste a bit of time and download bandwidth as
(upgraded or not) it will be removed in the next step.
I will leave this bug open as I have some ideas how to improve this code
area a bit in general, which might or might not work and might or might
not "solve" this (future me: pkgDepCache::Is{Install,Delete}Ok overload)
but that will be bookworm material.
In regards to the mariadb versioned packages and the potential for
upgrade problems they produce I had recently talked to its maintainer,
so I doubt that will change any time soon…
