NavMeshPath sometimes returns bad paths when using Obstacle Carving

AI Navigation


How to reproduce the issue:
1. Open the attached project
2. Open the "NavBug" scene
3. Enter Play mode
4. Navigate to the area with text "Mouse around here"

Actual result: The generated path is wrong (screenshot attached).
Expected result: The path should be generated correctly.

Reproducible with: 2018.1.0b1, 2017.3.0f3, 2017.2.1p1, 2017.2.0b1.

The bug is caused by the Sphere which has NavMeshObstacle.Carve set on.
The wrong path occurs when the path is going through the corner point of NavMesh Surface.
Couldn't test 2017.1 and earlier versions because of the compile errors.
