I haven't been able to answer this question by looking into the Tor Browser design document,
maybe you have an answer:

imagine you have two tabs in Tor Browser:

1: torproject.org (circuit A)
  embeds some youtube.com content

2: google.com  (circuit B)
  embeds some youtube.com content

it will route the TCP connection via two distinct circuits (A and B) as described in the design 
document [1]

Will DNS resolution be isolated using the same logic?

torproject.org and youtube.com will be resolved via circuit A
google.com and youtube.com will be resolved via circuit B

Is that correct?
