+  Scenario: Asynchronous Trace Continuity
+    Given I have a default Gotenberg container
+    Given I have a webhook server
+    When I make a "POST" request to Gotenberg at the "/forms/pdfengines/flatten" endpoint with the following form data and header(s):
+      | files                       | testdata/page_1.pdf                                     | file   |
+      | Gotenberg-Webhook-Url       | http://host.docker.internal:%d/webhook                 | header |
+      | Gotenberg-Webhook-Error-Url | http://host.docker.internal:%d/webhook/error           | header |
+      | traceparent                 | 00-0af7651916cd43dd8448eb211c80319c-b7ad6b7169203331-01 | header |
+    Then the response status code should be 204
+    When I wait for the asynchronous request to the webhook
+    Then the webhook request header "traceparent" should carry trace id "0af7651916cd43dd8448eb211c80319c"
