// lastErrorContext is lastError for a call made on behalf of ctx. A native cancellation (the call
// was aborted because ctx ended) is reported as ctx's own error, so errors.Is(err,
// context.Canceled) and errors.Is(err, context.DeadlineExceeded) hold. Any other native error is
// returned as is, joined with ctx's error when ctx ended during the call.
