SpriteShapeController.OnWillRenderObject() is ~20 ms when using SpriteShapeController.BakeMesh() and never updating the spline

Reproduction steps:
1. Open the attached project "ReproProj"
2. Open the “/Assets/Scenes/SampleScene.unity” Scene
3. Enter the Play Mode
4. Open the Window > Analysis > Profiler
5. Click "CPU Usage" row
6. In Profiler’s Hierarchy, search for “SpriteShapeController.OnWillRenderObject() [Invoke]”
7. Observe Time ms

Expected result: Time ms is less than 20ms
Actual result: Time ms is ~20ms

Reproducible with: 2022.3.61f1, 6000.0.47f1, 6000.1.1f1, 6000.2.0a9

Reproducible on:
