Is Physics.IgnoreCollisions working in webgl?

I built a jeep with wheels and the wheels are colliding with the jeep body in webgl, but not in the mac editor.
I’m using the IgnoreCollision code below and tracking the collisions with OnCollisionEnter code. On the mac editor I see no collisions.

//gameObject is the jeep body, wheel is one of the wheels:
Physics.IgnoreCollision(gameObject.GetComponent(Collider),wheel*.GetComponent(Collider),true);*

But it doesn’t seem to register in webgl
Is there a reason it would give a different behavior on webgl?

Found the problem and it wasn’t Unity. I was loading two of the same objects on top of each other.
