Reproduction steps:
1. Open the attached project: "1419316.zip"
2. Go to Project window > Assets > Scenes, and open "SampleScene"
2. Run the Project
3. In Scene View move GameObject "CylinderTrigger" closer to "Character" GameObject

Expected result: GameObject with Character Controller should be able to move through multiple GameObjects with Colliders and "Is trigger" toggled on
Actual result: GameObject with CharacterController falls through the platform it's stood upon when multiple GameObjects with Colliders are nearby

Reproducible with: 2019.4.37f1, 2020.3.33f1, 2021.3.2f1, 2022.1.0f1, 2022.2.0a12

Note:
- Reproducible independently of whether "Is trigger" is toggled on or off on a Collider
- Cylinder GameObjects have many duplicates of themselves as children
