It seems that it works if instead of using the default rejection handler i
use an explicit rejection handler as an inner directive.
respondWithHeader(`X-Request-Id`(requestId)) {
handleRejections(RejectionHandler.default) {
...
But this is rather inconvenient because some headers are set deeply nested
within the routes. Is there an better way?
