Comment (by sysrqb):

 Replying to [comment:7 gk]:
 > But now you get another set of those .onions as hosts in response
 headers. If they are not seen before the first (while validation is
 ongoing validation of other alt-svc hosts in headers seems to be skipped)
 gets validated again, causing another set of HS related circuits created
 and thus the circuit display is updated again. And so on with further
 posts.

 See ticket:27502#comment:15

 It seems gk already noticed this, too - but I think there is another bug
 hidden in there, too. I haven't found it yet, though.
