Pin layer to camera still not working

7 years ago I posted that pin layer to camera wasn’t working properly. It still isn’t.
In 2D mode I want to pin 3 layers to the camera. Then using static camera I want to zoom the camera in a little keeping my layers pinned to the camera. But for some reason SBpro chooses to move these layers visually to the bottom of the stack even though they are the top three layers.
There is no logic to this. Toon boom as I remember think this makes sense for some mathematical reason but it makes no sense and renders the option to pin layer to camera useless. Any one else suffer this ?
