     *
     * If the server does not respond to each ping with a pong within `interval`, this client will
     * assume that connectivity has been lost. When this happens on a web socket the connection is
     * canceled and its listener is [notified][WebSocketListener.onFailure]. When it happens on an
     * HTTP/2 connection the connection is closed and any calls it is carrying
     * [will fail with an IOException][java.io.IOException].

    canceling calls would cause the shared HTTP/2 connection to be unnecessarily released. This
    harmed connection reuse.
 *  Fix: Ensure canceled and discarded HTTP/2 data is not permanently counted against the limited
    flow control window. We had a few bugs where window size accounting was broken when streams
    were canceled or reset.
