Description
In VVC D7 vB, coding group size for chroma residual_ts_coding is set to 2x2 in case of Nx2 chroma block as indicated below:
log2SbSize = ( Min( log2TbWidth, log2TbHeight ) < 2 ? 1 : 2)
But in VTM7.0rc1, coding group size in such case is set to 8x2, aligned with regular residual coding case.
So it's suggested to align the spec text with VTM.

Thanks for reporting! I will it it in JVET-P2001-vC by introducing log2SbW and logSbH as for the regular coding case as follows:
