See here: https://github.com/RobotWebTools/rosbridge_suite/issues/138
It seems like it is actually a bug in rospy (which rosbridge_suite is written in). Apparently unpublishing has been broken since 2013 (https://github.com/ros/ros_comm/issues/111). So the issue does not arise when your client unpublishes/unsubscribes from the rosbridge server, but when the rosbridge_server itself unpublishes the ros topic.
A workaournd is to set the unregister_timeout argument to a huge value. Like 1 year, so rosbridge_server never unpublishes any topics. If you are publishing/subscribing and unpublishing/unsubscribing from a lot of different topics, this might become a problem over time.
This situation is quite dissapointing in my opinion.
