### System information

Godot v4.1.1.stable - Windows 10.0.19045 - Vulkan (Mobile) - dedicated NVIDIA GeForce RTX 2070 SUPER (NVIDIA; 30.0.15.1295) - Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (6 Threads)

### Issue description

When undocking the script editor so that it's floating, CollisionShape3D Shape Size handles stop working.

If they were visible on a Shape, they remain visible on that shape and still work for that shape; but they will not appear on any other collision object when selecting it.

If you launch the editor with the Script panel already in a floating state, no shape handles ever become visible.

If you dock the Script editor again, everything goes back to normal and works fine.

### Steps to reproduce

Create a 3D scene with some collision shapes.
Undock the Script editor
