> So, here is an interesting issue: If you load the website the first time
the circuit display actually shows part of the onion circuit (the one the
client controls) *but* the website still says that the content got loaded
over the regular Tor circuit. This is true. What happens is that a second
request is issued for the favicon which uses the onion in the alt-svc
header which then updates the circuit display even though the content did
not get loaded over the .onion. What should the display show here?
This is actually a circuit display issue (which we should deal with,
though) in the sense that it does not show any alt-svc routing requests at
all using the Cloudflare .onion service. This happens because once the
Alt-Svc header is processed the mapping is created and part of that is
validating it (see: `AltSvcCache::UpdateAltServiceMapping`) which means in
the https:// case just establishing a connection to the alt-svc host. And
the circuit display gets in turn updated with the client side rend circuit
caused by that validation request.
