3D Framed Camera stick to Non-physics target

[Hemerocallix]

Issue description

When follow mode is "Framed" and the dead zone isn't 0, and the target node is a non-physical node (eg. Node3D).
The camera will stick to the target node on start.
And keeps showing the errow message
E 0:00:02:496 phantom_camera_3d.gd:1068 @ _set_follow_position(): Condition "p.d == 0" is true. Returning:

While switching the node type to physic node (eg. CharacterBody3D). And it would work properly.

I don't know if I handle it properly,

Steps to reproduce

Create a scene and add a Node3D and phantom camera nodes
Set target node as the Node3D and set dead zone to any value other than zero
Run the scene and the camera will move directly into the target rather than keep a distance

And if you set physics_interpolation to on, the error message won't show up, but the camera will still stick to it.

Thanks for the report! Am in the middle of refactoring this specific Follow Mode, so will test against this once the new system becomes functional.
