Reproduction steps:
1. Open project “Character Controller Slope Bug”
2. Open scene “Playground”
3. Enter Play Mode
4. Using the "PlayerCapsule", attempt climbing up an orange cylinder (Environment\Greybox\Primitives\Cylinder (1)) in the scene

Expected result: attempting to move up the orange cylinder will not work, because the Slope Limit is set to 0
Actual result: attempting to move up the orange cylinder will work

Reproducible with: 2020.3.44f1, 2021.3.16f1, 2022.2.2f1, 2023.1.0a25

Reproducible on: macOS Catalina 10.15.7 (Intel)

Notes:
- The orange cylinder (Environment\Greybox\Primitives\Cylinder (1)) has a Capsule Collider attached
- The blue cylinder (Environment\Greybox\Primitives\Cylinder (3)) has a Mesh Collider attached with a Capsule Mesh for the collision, attempting to move up the blue cylinder will not work
- If the First Person movement doesn't work on some of the versions (with “Starter Assets package is missing dependencies. Please use Tools/Starter Assets/Reinstall Dependencies to fix it” error thrown in the console) adding “STARTER_ASSETS_PACKAGES_CHECKED” to “Edit\Project Settings\Player\Other Settings\Script Compilation/Scripting Define Symbols” fixes the issue
