System Information
Operating system: Windows-10-10.0.22635-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 551.86

Blender Version
Broken: version: 4.2.0 Alpha, branch: main, commit date: 2024-03-29 20:42, hash: d7c718dfd467
Broken in 3.6, 4.0, 4.1
Worked: (newest version of Blender that worked as expected)

Short description of error
The viewport rotation point does not work correctly if you rotate the view around selected curves, even if you select Orbit Around Selection in Navigation.

Exact steps for others to reproduce the error
1.
I use Blender without addons or custom settings.

Create a cube in the center, then move it above the Origine point in mesh editing mode.
Create a curved hair object attached to the cube. Add curves to the mesh.
In the settings, enable Orbit Around Selection (the expected behavior is rotating the viewport view around the selected curves or the volume of curves).
Rotating the viewport view does not work in curve sculpting mode, but if you switch to curve editing mode, the rotation is carried out correctly. Viewport view behavior is not consistent with editing in other modes.
I don’t know if this is a technical limitation or if the developers intended the design so that the hair will be in the center of the world and the viewport view will move accordingly. When developing characters, it often turns out that the part with the hair is located above the 0.0 point of the world, which creates great difficulties with camera control.
If you move the Origin of the curve object and the mesh to their volumes, the bug still remains.
As an example, I am attaching a file created in Blender 4.2 with a mesh and curves.
