> Listeners added with `sparkSession.streams.addListener(l)` are added to a SparkSession. So events only from queries in the same session as a listener should be posted to the listener.
> Currently, all the events gets routed through the Spark's main listener bus, and therefore all StreamingQueryListener events gets posted to StreamingQueryListeners in all sessions. This is wrong.
