Blender Version
Broken: version: 2.83 (sub 15), branch: master, commit date: 2020-04-29 19:35, hash: rBcd833d887995
Worked: (newest version of Blender that worked as expected)

Short description of error
If you parent the camera with an object, and you go into camera view with "0" key, the movement of the camera will also move the parent object

Exact steps for others to reproduce the error
Place a camera, place a cube, Parenting Camera with Cube, enter in camera view, and activate "Lock camera to view", now if you move the camera with the mouse, the camera will also move the object interacting with the mouse to move the Camera. (It will always remain proportionate to the camera, as fixed)
This does not happen by changing the position of the camera from the "item" -> transform panel
