LevelChangePropagator propagates changes made to the level of any logback-classic logger onto the java.util.logging framework, but it ignores levels set before the installation of the listener.

I'd like to propose that when LevelChangePropagator is installed, it allows the initial configuration as defined in logback.xml to override the initial configuration of JUL. Meaning, if the same logger is configured in JUL and Logback, the level declared in logback's configuration should win.
