Reproduction steps:
1. Open the attached “Bug.zip” project
2. Open the “SampleScene” scene
3. Open the Frame Debugger Window (Window > Analysis > Frame Debugger)
4. Enable the Frame Debugger
5. On the slider at the top go through Events and observe the Output screen

Expected result: The cubes in the center are rendered based on their RenderParam.renderPriority value
Actual result: The cubes in the center have the same render priority as Mesh with layer order set to “0”

Reproducible with: 2021.3.37f1, 2022.3.23f1, 2023.2.18f1, 6000.0.0b14

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

Note:
- The generated cubes get rendered in-between “Mesh Cube red S0” and “Mesh Cube blue S0” which both have their “Order in Layer” set as “0”
- The mesh draw script is attached to the “Bug” GameObject in the Hierarchy
