here is what i found:
16.7 Response Processing
6. Choosing the best response
Otherwise, the proxy MUST forward a response from the responses stored
in the response context. It MUST choose from the 6xx class responses if
any exist in the context. If no 6xx class responses are present, the
proxy SHOULD choose from the lowest response class stored in the
response context. The proxy MAY select any response within that chosen
class. The proxy SHOULD give preference to responses that provide
information affecting resubmission of this request, such as 401, 407,
415, 420, and 484 if the 4xx class is chosen.
so it would be perfectly ok to select 487 over 486 and looks like it
would solve the problem.
