Bluetooth audio stopping when app not in focus?

On build 17A291m.


When I'm using my Bose QC30 bluetooth headphones, the bluetooth audio is having problems.


In Safari & Chrome, if the tab with audio (e.g. youtube video) is not in focus (if I switch tabs while the video keeps playing), the audio to the bluetooth headphones stop, while the video itself keeps playing in the inactive youtube tab.


I can tell that this is an OS-wide issue as I tried playing a video on VLC, and when I switched focus to another application, the audio also stopped like it does when I switch tabs in web browsers.


Can anyone verify this issue on their mac?
