When drawing 3D widgets with the Gizmo/GizmoGroup API, with the "DEPTH_3D" bl_option on the GizmoGroup, the widget loses its depth culling when mouse hovered.
Exact steps for others to reproduce the error

Can confirm.
The test files aren't working here, if I zoom out I can highlight geometry above the mesh
That's odd, I couldn't reproduce that with the version of the addon and file that was attached, on Blender 3.2. Still, I uploaded a slightly newer version of the addon and tweaked version of the file and edited the original post. I hope that works properly, but even if not, you should be able to see the culling issue by just spawning a default cube between wherever the gizmo appears, and your camera, so the cube partially (or even fully) obscures it. If you hover your mouse over the cube, the gizmo will become highlighted, and fully visible through the cube.
Has this worked in previous versions btw.?
Sorry I didn't see that message back in... May. Not that I know of, no, but I was finding these issues as I was developing this gizmo add-on for the first time, so I could be wrong.
