We could try to change it to: AVAudioSessionCaptureDevice isolatedCopy() &&;

> Source/WebCore/platform/mediastream/ios/AVAudioSessionCaptureDevice.mm:61

If we go with isolatedCopy() &&, doing WTFMove(m_persistentId).isolatedCopy(),
WTFMove(m_groupId).isolatedCopy() will most probably remove the memory
allocation of a new string.
