DefaultRenderingPipeline remove camera in list

Hi,
Not sure if it's a bug (rather an observation), but when I'm using BABYLON.DefaultRenderingPipeline(), it remove cameras from the given array.
I think the function should make a copy of the given array, because if I give scene.cameras, the function remove cameras from the scene.

Here's the PG: https://www.babylonjs-playground.com/#KZZ4TI#1

Thank you !!
