System Information
Operating system: Linux-5.13.0-0.rc6.45.fc35.x86_64-x86_64-with-glibc2.34.9000 64 Bits
Graphics card: NVIDIA GeForce GTX 970M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 495.44

Blender Version
Broken: version: 3.2.0 Alpha, branch: master, commit date: 2022-03-04 07:44, hash: 5eaeb9bd0d
Worked: 2.93

Caused by b9febb54a4

Short description of error
The original curve line for curves is not displayed in wireframe display mode.
This change only applies when the curve is changed during evaluation, for example, when it is replaced by an evaluated "tube" mesh, or points, or a volume, etc.
This is very similar to #96138 (Regression: Curve wire line not displayed in edit mode when it has evaluated mesh/point/volume), but for objectmode.

Exact steps for others to reproduce the error

create a curve
in the curve properties, give it a bit of extrude
enable viewport shading wireframe OR
enable object Viewport Display properties > Wireframe

Personally I don't think this is a bug at all (the curve doesn't exist at all in the evaluated state of the object, it was replaced with a mesh).
I understand there is some nuance here though, especially as Blender never distinguished very well between the two in the past, so this still may be expected for some users.

Either way though, I don't think I see anyone spending time to fix this now, since the curve object is actively being replaced (#95355).
