Motion Vectors are not applied to the GameObjects when they're rendered through Terrain

How to reproduce:
1. Open the attached "case_1372553" project
2. Open the "OutdoorsScene" Scene
3. Observe the Game view in the Play Mode

Expected result: The Motion Vector is applied to the grass/foliage. No severe ghosting and blurriness is observed
Actual result: The quality of motioned grass/foliage that is rendered through Terrain is severely ghosty and blurred. The higher the "Camera -> Rendering -> Quality Preset", the worse and blurry the quality of the GameObjects

Reproducible with: 10.7.0 (2020.3.24f1), 12.1.2 (2021.2.6f1), 13.1.3 (2022.1.0b2)
Couldn't test with: 7.7.1 (2019.4.33f1) (project files got corrupted due to downgrading)
