Description

https://github.com/apache/logging-log4j2/blob/rel/2.17.2/log4j-core/src/main/java/org/apache/logging/log4j/core/filter/RegexFilter.java#L58-L61:

public Result filter(final Logger logger, final Level level, final Marker marker, final String msg,
        final Object... params) {
    return filter(msg);
}

This code does not parameterize the message when useRawMsg is false.
