 If I visit foo.com and look at its source (e.g. via Ctrl + U) another
 request is sent over the Tor network using "--NoFirstPartyHost-about-
 blank--" as SOCKS username. There are two things wrong with that behavior:
 1) view-source requests should not hit the network at all as this is not
 necessary. 2) All these requests are sent over the same circuit allowing
 user profiling which the isolation to the URL bar domain should prevent.
