max_statement_time fails from configuration file, documentation lacking

I created a test SQL query to do some basic counting for internal debugging purposes (confirmed duplicates) and it turned out to be a very long running query that I stopped tracking about after five minutes.

So I simply wanted to update the configuration file to automatically stop the execution of excessively long-running queries.

I did manage to get it working through the CLI call set in the Windows registry, here is a minimized version of that call:

"C:\MariaDB\bin\mysqld.exe" "--defaults-file=C:\MariaDB\data\my.ini" "--max_statement_time=4" "MariaDB"

However setting max_statement_time in my my.ini configuration file fails! Additionally it is not documented for the configuration file here: https://mariadb.com/docs/server/ha-and-performance/optimization-and-tuning/system-variables/server-system-variables#max_statement_time

Windows installs will ultimately fail sooner or later and have to be reinstalled. That is why the internal configuration file is far superior. Just like blocking a number on a phone is almost pointless since you'll get a new phone in three or four years however adding a Z at the start of their contact means when you import your contacts to the new phone and a bad contact calls you then you know not to pick up.
