 When a partial refresh request is made, if the response has an error code
 the partial will invoke its fall back behavior, normally resulting in a
 full refresh. A 404 status is considered an error code by the selective
 refresh JS, and so this means that attempting selective refresh on the 404
 template will currently always result in the fallback behavior ensuing.
