Comment (by bugzilla):

 Lag of changing circuit in circuit visualizer is so obvious that I
 preferred not to go deeply into the problem (sorry). It's good that Tor
 has full support of prefetching, but the ticket is about Tor Browser, UX
 and, maybe, its integration with Tor.
 If circuit is prefetched, then it will be good if user can see it in a new
 tab, even if no page was loaded.
 The main proposal is to make circuit visualizer that shows situation with
 circuits in real-time.
 There is a ticket close to this: no visual circuit if SSL error or
 similar. It complements this ticket in a part of preserving visualization
 of the current circuit until new circuit will be allocated to the tab.
