        // This can happen if the server reduces MAX_CONCURRENT_STREAMS while we already have notifications in
        // flight. We may get multiple RST_STREAM frames per stream since we send multiple frames (HEADERS and
        // DATA) for each push notification, but we should only get one REFUSED_STREAM error; the rest should all be
        // STREAM_CLOSED.
