Description
Section 8.4.5.2.6 includes the following condition:
BdpcmFlag[ xTbCmp ][ yTbCmp ][ cIdx ] is equal to 0;
For chroma, the index [xTbCmp][yTbCmp] used here is a chroma component position. However, everywhere else in the text BdpcmFlag is stored and referenced using a luma position.

Good catch, thanks! I suggest to fix it as follows:
BdpcmFlag[ xTbCmp * ( cIdx > 0 ? SubWidthC : 1 ) ][ yTbCmp * ( cIdx > 0 ? SubHeightC : 1 ) ][ cIdx ] is equal to 0;
