In general, it typically is used to confirm support for an option so it’s especially wrong. 

One way to catch this bug may be reflect EDO with 3 bytes. The bad part is that it might not fit in the option space in the SYN-ACK (if it barely fit in the SYN, eg). 

I think this should just be a bug that is reported or fixed, though.
