Module-specific log level configuration not working properly

[studersi]

When we raise the global log level in Apache, we can see a lot more [sts:debug] entries than when we raise it only for mod_sts.

For example, we can see all sorts of debug messages when we use the following configuration:

LogLevel trace7

However, with the following configuration, we can only see these log entries:

LogLevel notice sts:trace7

[2026-01-07 07:34:15.035928] [sts:debug] - - sts_post_config: enter
[2026-01-07 07:35:00.504282] [sts:debug] - - sts_child_cleanup: enter

This behaviour was observed and reproduced for mod_sts-4.1.0-liboauth2-2.1.1.
