Yes. I've added logging to the code where it serializes data into the
buffer for writing, and at that moment, on a P device, it is not being
truncated. I haven't yet done a similar check for pre-P devices, so if you
let me know what version you are seeing the truncation behavior on, I can
pull out the sniffer and investigate further.
