The loopback handlers in `transport_test.py` read and discard the POST body and no transport test passes `params`, while the wiring tests send `json=` through a patched request. Could a loopback test send a POST with `json={"query": "{ ok }"}` and `params={"page": "2"}` and assert that the server receives that decoded body and query string? -- This is an automated message from the Apache Git Service.
