156	M0464 integration applies transform skipping to chroma	bheng		"The integration of M0464 that ""limits TS to luma transform blocks as well as extends it to transform block sizes up to 32x32"", is still applying transform skipping to chroma blocks.

Specifically, in file TrQuant.cpp, invTransformNxN() and transformNxN(), the condition:

    if( tu.mtsIdx == 1 )

doesn’t check whether the current component is actually luma or not.  So, the chroma transform units will use the mtsIdx for luma and can still apply transform skipping.
