Thank you for the fix, but if 2 camera is created, and showing the `CameraGizmo` of one camera while the other camera is active, the active camera’s maxZ will be changed. Is this something expected? Why should there be this behavior?

Ok.  
Steps to reproduce:

1. Open the empty playground [https://playground.babylonjs.com/](https://playground.babylonjs.com/)
2. Open Inspector
3. Right click on “Nodes” - “Add new free camera”
4. Click “camera1”, the value of “Far plane” should be 10000
5. Click “Turn on/off the camera’s gizmo” of “free camera”, the newly created camera
6. Watch value of “Far plane” changes (Current selected node is still “camera1”)

Expected: value of “Far plane” not changed  
Actual: the image above [CameraGizmo changes maxZ every time it shows - #5 by kzhsw](https://forum.babylonjs.com/t/cameragizmo-changes-maxz-every-time-it-shows/57966/5)
