Simply put, just don't, and if you really insist on it, the workaround for the time being to make it work with some duplication of settings is the extra handlerPrefix setting that's mentioned in the bug. It's meant as an optimization to let the code run quicker but it's mandatory for the time being when the URL is changed.
