Replication from MySQL 5.7 Master to MariaDB 10.6 Galera Cluster breaks

When we try to migrate from MySQL 5.7 to a MariaDB 10.6 Galera Cluster using the Master/Slave replication the Galera Cluster immediately falls apart after the first CREATE DATABASE statement.

How to reproduce:

On Master:

CREATE DATABASE xyz;

root@localhost [(none)]> show databases;
--------------------

--------------------

--------------------

On Galera Slave node the database is there but Cluster falls apart immediately:

and the database is NOT on the other Galera nodes... This breaks our whole migration path from MySQL to MariaDB.

In the error log we can see:

There is another minor error:
event_type: -94 -> this should not be UNSIGNED but SIGNED (162)

We can reproduce it at will (we have done it twice).
