How to reproduce:
1. Open the “URP_ForwardPlus_Improvements_Issue” project
2. Open the “Assets/CustomProjectionMatrix bug/CustomProjectionMatrix bug.unity“ scene
3. Enter Play Mode
4. Open the Rendering Debugger (Window > Analysis > Rendering Debugger)
5. In the Rendering Debugger window open the “Material” category
6. Under the “Materiela Filters” change the “Material Override” field from “None” to “Lighting Complexity”
7. In the Game view window observe the “Quad” GameObject

Expected result: There are 5 purple areas
Actual result: There are 3 purple areas

Reproduced with: 2022.3.15f1, 2023.2.4f1, 2023.3.0a19
Could not test with: 2021.3.33f1 (URP Rendering Path "Forward+" is not available)

Reproduced on: Windows 10 (by reporter), Windows 11
Not reproduced on: No other environment tested

Notes:
1. Could not test in HD RP → “Material Override” field does not have the “Lighting Complexity” option
2. Only reproducible when “Asset/Settings/URP-HighFidelity-Renderer.asset” Universal Renderer Data’s Rendering Path field is set to “Forward+”
