Comment (by TBD.Chen):

 Although this is a tradeoff, we can just add the circular detection to
 prevent that.
 The hidden service can just send a requestion to itself and check whether
 it can receive the requestion.

 Replying to [comment:11 asn]:
 > I've been thinking of closing this ticket, mainly because this is a
 ticket we are aware of, and a tradeoff we took on purpose. I'm leaving it
 open just because it could be relevant to #25754.
