Can Safari access camera in multiple concurrent tabs?

It is a known issue with Safari that when you use multiple tabs at once, the browser cannot access the camera. This happens because Safari allows only one tab to access your microphone and webcam at any given time. If you open another tab and join a webRTC session, the video on the initial tab will turn black. You can detect when the camera is taken away by listening to the 'pause' event on the video element.
