Automatic LOD fails and SRP Batcher incompatibility occurs when using spline-based quad-topology meshes

Reproduction steps:
1. Open the attached “IN-120025” project
2. Open the “Scenes/SampleScene” Scene
3. Observe the “Quads” GameObject in the Scene View

Expected result: The “Quads” GameObject applies automatic LOD correctly and remains compatible with the SRP Batcher
Actual result: The “Quads” GameObject using spline-based quad topology does not apply automatic LOD and is not compatible with the SRP Batcher

Reproducible with: 6000.0.60f1, 6000.2.8f1, 6000.3.0b5, 6000.4.0a2

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Note:

• Visible results might be different depending on the machine it’s being tested on
