Dear all,

On iOS 18 even though bluetooth is connected, WebRTC video call still does not automatically select Airpod microphone and Airpod speaker.
It selected iPhone micro and  Iphone speaker.

Tested devices:
- iPhone 14 pro, iOS 18 with AirPod pro

Expected:
- Incoming and outgoing audio through the Airpod microphone and Airpod speaker.

Bug is still reproducible on iOS/iPad 18.0.1
