That doesn't help. In fact I have changed ssl/quic/qlog.c:
  static void qlog_event_epilogue(QLOG *qlog)
  {
+    int ret;
      ossl_json_object_end(&qlog->json);

      ossl_json_key(&qlog->json, "time");
@@ -390,6 +391,11 @@ static void qlog_event_epilogue(QLOG *qlog)
      }

      ossl_json_object_end(&qlog->json);
+    ossl_qlog_flush(qlog); /* best effort */
+    ret = BIO_flush(qlog->bio);
+    if (ret) {
+      printf("rate!\n");
+    }
  }

Now I have my trace:

So chrome is sending a setting which the ossl-nghttp3-demo-server 
doesn't like :-(
