### System information

### Issue description

A CSGPolygon3D node with 'use_collision' on, in Path mode, with a path node assigned, throws the error "Node3D::get_global_transform: Condition "!is_inside_tree()" is true. Returning: Transform3D()" when running (and in some cases when switching scenes).

~~In this same MRP you can also see a different error, when switching between scenes in the editor, that I've mentioned in https://github.com/godotengine/godot/issues/58869, I can open a separate issue if needed:~~
I've opened a separate issue for this in https://github.com/godotengine/godot/issues/71750.

### Steps to reproduce

Run the MRP. It's a simple Node3D scene with a CSGPolygon3D and Path3D as children.
