Why else mysql-common next to mariadb?

Question

MySQL

apt list --upgradable shows

...
mariadb-common/testing 10.1.22-3 all [upgradable from: 10.0.30-0+deb8u2]
mariadb-server/testing 10.1.22-3 all [upgradable from: 10.0.30-0+deb8u2]
...
mysql-common/testing 5.8+1.0.2 all [upgradable from: 5.5.55-0+deb8u1]
...

Why else mysql-common? Where does it come from and why? I use only mariadb, as far as I remember, I didn't install mysql at all.
