 * keywords:   => robustness

Comment:

 Note that the topology corruption introduced will NOT be detected by
 ValidateTopology, but is easily spotted by looking at the left/right face
 labels of the longest edge which are clearly wrong. The lack of reporting
 by ValidateTopology is handled in #6065
