Mixed cached shadows on directional lights not working correctly when cascade count is set to "2"

Reproduction steps:
1. Open the attached user's project ("2023-beta-test")
2. Open scene "Assets -> SceneDirectionalLight"
3. Move the camera around the scene and observe the shadows

Expected result: The shadows are rendered without artifacts
Actual result: The shadows produce artifacts

Reproducible with: 2021.3.35f1, 2022.3.20f1, 2023.2.12f1, 2023.3.0b9

Reproducible on: macOS 14.2.1 (Intel), Windows 10 (User)
Not reproducible on: No other environment tested

Note:
There's a second project called "OnDemandShadowMapUpdate" attached that might help with reproducing the issue.
