Actually, it does.  I reported on this in a message to the reflector titled "TX 
Test Mode Garbage"  dated 7-25-2017

As a follow up Wayne wrote:

Hi Wes,

TX TEST mode activates the entire TX strip because it turns on PTT to test the keying of downstream devices. This was requested by our original field testers. The only thing that isn’t turned on is the carrier. It could be that in SSB modes there’s noise in the voice passband, producing the result you observed.

I can clarify this in an errata item for the owner’s manual.

It may also be possible for me to disable the TX AF path via a DSP command, and I’ve added that to the firmware task list.

Thanks for the input--

Unfortunately, as I responded, I first observed it in CW mode, and I had at the 
time, confirmation from three other guys who observed a similar situation.
