QML Camera: Camera selection not updated correctly

QML Camera example.

On a computer with multiple cameras (e.g. built-in and external), one can use a button to switch the active camera.
In principle that works, but when switching between still photo and video screen, the camera selection is not updated correctly.

1. open QML Camera example
2. select a different camera in the UI (e.g. from built-in to USB camera)
3. switch to video

Expected: The camera selection uses and shows the previously selected USB camera in the UI
Actual: USB camera is still used, but the built-in camera is selected

Looks like the buttons are separate in the two UIs (still photo vs video), but not updated to match each other.
