The likely reason for this is that with a smaller MSS you have more
segments per window, and because we ACK every other segment you have
more ACKs per window, and so the effect of any one ACK being lost is
diminished - you'll probably receive another one soon after the lost one
and so be able to carry on as ACKs are cumulative.

No, this is not the right solution.
