Fix T88478: Fallback to dolly not working when moving the camera in camera view

This fallback is an old hack.

It is difficult to have an orientation convention when several random
factors determine which one should be used.

In this case, to "fix" the problem, a new behavior had to be implemented.
Now the redo when moving the camera in `Camera View` has the default
orientation as `View`.
