How to reproduce:
1. Open the attached “IN-94755_LineRendererTest“ project
2. Open the “SampleScene“ and enter Play Mode
3. Select both the “Line” GameObject under the “Accurate Collider, Camera Y Rotation 0“ GameObject and the “Line” GameObject under the “Inaccurate Collider, Camera Y Rotation 90“
4. Observe the result

Expected result: Both “Line“ GameObjects have a MeshCollider that matches the shape of the “Line“ GameObject
Actual result: The “Line” GameObject under the “Accurate Collider, Camera Y Rotation 0“ has a MeshCollider matching its shape, while “Line” GameObject under the “Inaccurate Collider, Camera Y Rotation 90“ has a MeshCollider in the shape of a box
