Not a huge fan of this hack, but setting
lib/get-url (which is needed to get the right CDN URL) makes our
ajax lib prepend the subfolder path to all the requests it makes which makes pretender unable to recognize our fixtures. One alternative fix is to add an
isTesting() check in our
ajax lib here and if we’re in test mode then we skip the
getURL call, but I’m not a fan of that approach either.
