Not all bounding box vertices are draggable #9869

Describe the bug
I want to change the size and orientation of a bounding box by dragging the displayed vertices. Unfortunately, it appears that only a random subset of the vertices can actually be selected, as shown in the attached video.

To Reproduce
Steps to reproduce the behavior:

1. Create a new project using the "Object Detection with Bounding Boxes" labeling interface
2. Start labeling an image
3. Create a bounding box
4. Try to drag or rotate the bounding box

Expected behavior
All the vertices can be selected

As you can see in the video above, in this example, only 2 out of 9 vertices can be selected

Environment (please complete the following information):

• OS: Ubuntu 24.04.4 LTS x86_64
• Label Studio Version 1.23.0
