Only one built-in webcam is selectable with dual display setup (Apple Studio Display)

Anyone else running two identical displays with inbuilt webcams seeing this issue?

When connecting two Studio Displays to an MacBook Pro (M1), in the Video Camera selection there are two entries for the Studio displays with identical names. 

Selecting either "Studio Display Camera" always sets the video feed to come from the designated Main display. It does not allow selecting the Extended display camera.

Same issue here, although in my case it is the Extended display camera that is used.

I think what happens is that the order you connect the displays determines the one Zoom uses.

Try connecting the one you want to use with Zoom first, this odd work-around seems to do it for me.
