errorMessage dropped the response body, so .body/.full in
errorLoggingComponents only affected the request body — 4xx/5xx response
bodies (e.g. Google's error.errors[].reason/location) never reached the
logs and failures were unattributable. Thread statusCode + data through
logRequestFailed into errorMessage and render the body when the body
component is enabled.
