Both Utils, function bytecodeLenInWords and L2ContractHelper, function _bytecodeLen do calculate the length in words of a given bytecode like the following:
However, when hashing the bytecode, the bytes at position [2] are set to 0:
It seems that codeLengthInWords should be equal to the bytes at position [3] alone, as the variables name bytecodeLenInWords suggests, that is:
L2ContractHelper, function _bytecodeLen
Utils, function bytecodeLenInWords
