setDNS not in effect for css initiated resources?

I am using a script to force a site to go through my proxy and you can see my results here: http://www.webpagetest.org/result/130726_VH_47X6/

The strange issue here is that the setDns directive is in full effect for the HTML issued requests but any image request whose referer happens to be CSS, I do not see my setDns being honored.

Is this something to do with how setDns is implemented in the WPT Agent?

The following is the script in question

–
setDns cdn1.gilt.com a.b.c.d
navigate http://www.gilt.com

Thanks in advance for your help!

Looks like you need to use cdn1.giltcdn.com instead of cdn1.gilt.com
