Comment (by pastly):

 This bug doesn't reveal itself when descriptors are used. Just
 microdescriptors. Therefore sbws no longer has this bug.

 I switched to sbws 0.4.0 which hits this bug.

 3.5.2 and 3.5.3 hit it essentially immediately. 3.5.4 does not within 2
 hours.

 I'll check if anything in 3.4.X or 3.6.X is affected.
