It is very annoying and it is not just a pandora issue, but WP issue. I have had this happen to me while using other 3rd party music apps as well. Everytime the bluetooth connection is terminated, the phone seems to toggle play/pause. Idea seems like that IF you are playing music and bluetooth disconnects, music should pause. However, the downside is that when connection is terminated and you are paused... pause toggles to play!
