`Response.elapsed` not set

[stefanadelbert]

Problem
Response.elapsed isn't set after a mocked POST if add_response is given json=... or content=b....

Reproduce
This snippet replicates the problem for me:

def test_elapsed(httpx_mock: HTTPXMock):
    httpx_mock.add_response(json={})
    r = httpx.post(
        "https://jsonplaceholder.typicode.com/posts",
        data={"title": "foo", "body": "bar", "userId": 1,},
        headers={"Content-type": "application/json; charset=UTF-8"},
    )
    r.raise_for_status()
    r.close()
    print(r.elapsed.total_seconds())

Versions
httpx=0.21.3
pytest_httpx=0.15.0
