      Description

      Doing this should get rid of a scary (but harmless) looking browser console errors when the SSE connection is unexpectedly dropped e.g. by an intermediary proxy/gateway.

      By doing this periodically from the client side (disconnecting and reconnecting), we avoid the user seeing this.

      The error looks scary but is actually fine because the SSE EventSource auto-reconnects.

      Something to consider though .... we might need to do some sort of "store and forward" at the gateway for when messages arrive during a reconnect. See JENKINS-36238

            Not really needed now because we have the connection timeout set so low that this should no longer be an issue. Those scary browser console errors (as seen on dogfood) should be a thing of the past now too.
