FPSController's Y position jitters when walking through the middle of a large Plane GameObject

Physics

-

How to reproduce:
1. Open the Unity project from the link in the comments (JitterBug.zip)
2. Open the "SampleScene" Scene
3. Select the "FPSController" GameObject, open the Inspector window
4. Play the Scene, use the WASD keys to move left and right
5. Observe the Y position value in the inspector

Expected result: The Y position stays fixed, as this is a flat Plane
Actual result: The Y position increases by about 0,5 while walking over a specific spot

Reproducible with: 2017.1.0a1, 2017.1.4p1, 2017.2.3p1, 2017.4.5f1, 2018.1.4f1, 2018.2.0b8, 2018.3.0a1

Notes: This seems to only be an issue with larger Planes, as setting the plane's Scale to 1000x1x1000, for example, does not reproduce the bug
