Bug description

Hello,

After upgrading from v34.6.0 to v34.7.0, my application’s behavior changed due to an intentional modification introduced in this commit:
5523179c85d2576520ffeb1756bc3b30f6cf5fd6

feat(InteractorStyleManipulator): update center of rotation on pan
This enhances pan-then-rotate interaction.
After panning, move the center of rotation by the same vector that the camera position moved.
Before, if the user panned the camera, zoomed in, then rotated, they would rotate around a point
that was not in the center of the camera.

My use case :

• I display a group of actors.
• The interactor’s center of rotation is set to their center of mass (since vtkCenterOfMass does not exist in vtk.js, I calculate the center of mass manually).
• I want the center of rotation to remain fixed at this center of mass even after panning.

Problem :

With the new behavior in v34.7.0, the center of rotation moves after a pan, which breaks this use case.

Questions / Suggestions :

• Is there a way to opt-out of this new center-of-rotation update on pan?
• If not, could an option be added to preserve the old behavior?
• Since this change alters the default interaction model, it might be worth marking it as a breaking change in the changelog so users are aware.

Thanks in advance for your help !

Steps to reproduce

This is an example project https://codesandbox.io/p/devbox/hello-world-cone-forked-grwhjg with my behaviour
For simplification i use the center of the cone instead of the center of mass but the idea is the same

Detailed Behavior

On start, the cone rotates around its center
After a pan, it rotates around a point on the center of the viewer

Expected Behavior

On start, the cone rotates around its center
After a pan, it rotates around its center

Environment

• vtk.js version: 34.7.0
• Browsers: firefox
• OS: Mac os
