command prompt does not accept new line character \n in my.cnf

We upgraded some of our machines from 10.3 to 10.6 and noticed that mysql client / mariadb client command prompt looks different in 10.6 because it does not accept newline character \n

\n is documented in https://mariadb.com/kb/en/mysql-command-line-client/

In 10.3 we had

[mysql]

prompt = \u @ \h [\d]:\nmysql>\_

The prompt looks like this:

root @ localhost [(mydatabase)]:

mysql>

With the same settings in MariaDB 10.6 the prompt looks like this:

root @ localhost [(mydatabase)]:mysql>

The prompt is not wrapped to 2 lines.

I also tried to define it in section [mariadb-client] but nothing changed.

This is clearly a regression from the older versions.
