Game view fails to render when Cameras are stacked and STP is enabled

How to reproduce:
1. Open the “CameraStackSTP.zip“ project
2. Open the “SampleScene“
3. Observe the Game view

Expected results: The Game view is rendered correctly
Actual results: The Game view is not rendered

Reproducible in: 6000.0.27f1, 6000.1.0a4
Not reproducible in: 2021.3.46f1, 2022.3.52f1 (No STP in Upscaling Filters)

Reproduced on: Windows 11 Pro (23H2), macOS 15.1 (M2, by the reporter)
Not reproduced on: No other environment tested

Notes:

• Not reproducible with other Upscaling Filters
• If either of the Cameras in the Scene is disabled the Game view will be rendered correctly
• Could not test in HDRP as Camera stacking is not supported there
