System information

Godot v4.2.stable - Windows 10.0.19045 - Vulkan (Forward+) - dedicated AMD Radeon RX 7900 XTX (Advanced Micro Devices, Inc.; 31.0.23013.1023) - 13th Gen Intel(R) Core(TM) i7-13700KF (24 Threads)

Issue description

When a BoneAttachment3D node has override_pose enabled, the editor is not properly updating the bone transform if the BoneAttachment3D receives a global transform change but not a local one.

In the attached video you can see that the bone pose updates properly if i move the BoneAttachment3D node. But, when I move the parent node, nothing is happening to the bone. Then when I slightly move the BoneAttachment3D it will trigger the bone pose to update and snap to the correct position.

Steps to reproduce

Start at step 5 if using the minimal reproduction project

1. Set up a Skeleton3D
2. Add a new Node3D
3. Add a child BoneAttachment3D to the Node3D
4. Set up the external skeleton on the BoneAttachment3D and target a bone, set override_pose to true
5. Move the Node3D we created in step 2 and see that the bone pose does not update in the editor

(6. Move the BoneAttachment3D node slightly and see it teleport the bone to the correct position)
