Animation preview to undo stack is a total bummer

Hi,
Why the hell is the animation preview or even any of the frame previews making it into the undo stack?
This is a total waste it does nothing since McNeel can’t send me back in time to undo myself watching the preview why the hell is this making it into the undo stack.
Please see that this is fixed it’s really a bummer when trying to edit path curves to see how an animation is progressing. It might take many undos just to get back to a point edit of the animation curve because of the previews making it into the undo stack.
