Comment (by gk):

 Two questions:

 1) What was wrong with the former approach?
 2) Applying your patch to tor-browser, tagging it and running that through
 our gitian machinery produces at least Mac OS X bundles (or better:
 produces at least one Mac OS X bundle, en-US) that still has this issue
 (Windows builds have not finished yet). Any idea how this could happen? I
 used the URL in the description of this ticket for testing.
