* Given a correctly sorted list of materials, check if the
* opaque comparator can sort a reversed list of them.
*
* Each material will be cloned so that none of them will be equal to each other
* in reference, forcing the comparator to compare the material sort ID.
*
* E.g. for a list of materials A, B, C, the following list will be generated:
* C, B, A, C, B, A, C, B, A
, it should result in
* A, A, A, B, B, B, C, C, C

*
