 For HTTP-E 3.5.3 and 3.5.1 (neither seems to be an option in the Version
 pulldown?!), the more/less links for TripAdvisor reviews fail. For
 example, go here:

 http://www.tripadvisor.com/Hotel_Review-g56935-d99710-Reviews-
 Stone_Lizard_Lodging-Blanding_Utah.html

 Find a review that is too long for the initial view. Clicking on the more
 link at the bottom of the review fails.

 The HTML for these links looks something like:

 <span class="taLnk hvrIE6 tr210874369 moreLink ulBlueLinks"
 onclick="ta.util.cookie.setPIDCookie(2247);ta.call('ta.servlet.Reviews.expandReviews',event,this,'review_210874369',
 '1', 2247)">

 The link, or more precisely the onclick code, fails because the TA
 variable is not defined when HTTPS-E is enabled. Presumably TA stands for
 TripAdvisor and HTTPS-E is blocking whatever code defines this variable.

 My guess is that ticket #12063
 https://trac.torproject.org/projects/tor/ticket/12063#no1 is related with
 the same root cause.
