Incorrect Output of Incremental Portable SHAKE API

The incremental squeeze functions in the portable SHAKE XOF API, when attempting to squeeze more than RATE 168 for SHAKE128, 136 for SHAKE256 bytes, performed an additional permutation of the state before producing the first output block, thus discarding the first block of RATE bytes of valid XOF...
