    This bug is quite obscure and it's important to note once the capsule collider is able to pass through the cloth it may continue to work even after the Sphere is removed.

    To reset the problem all colliders have to be removed from the cloth.
    Adding the ThirdPersonController capsule collider to the cloth it will still fault.
    By also adding the Sphere collider to the cloth the character can then walk through and move the cloth in both directions.

    Here's a video of the bug in action:

    As the project in this issue didn't convert properly for me in 2018 release here's the Unity Package.
