#
# Technically we'd check that Turbolinks-Referrer request header is
# also set, but that'd require us to pass the header from post/patch/etc
# test methods by overriding them to provide a `turbolinks:` option.
#
# We can't check `request.xhr?` here, either, since the X-Requested-With
# header is cleared after controller action processing to prevent it
# from leaking into subsequent requests.
