Wireless Android Auto - music keeps playing on handset after disconnect

V3 build 838. Samsung Note 9 - Pie.

To enable Wireless Android Auto I am using Google Play services beta and an Android Auto APK not yet released on app store. I accept that these are beta features and could well be the cause of the issue.

Issue does not occur when using Android Auto wired.

There is couple of events Poweramp should (and it does) accept to stop playing on various devices disconnections, and there is no anything new added for Android Audio in this regard. Either this is oversight on Google side or there is some undocumented API. Does Google Play Music pause for you on such disconnection. Thanks!
