On the backend, the events endpoint caches responses by ETag in order to reduce the load on the database and response times. That cache is supposed to be invalidated with the middleware receives a notification that the underlying data has changed. However, that change might arrive just *after* the HTTP request, meaning that if we let the browser do its thing we will probably be returning stale data. So what we do is we explicitly request a non-cached response when we know that something has changed because we changed it ourselves. What we do not do is bypass the cache if we receive a change event notification, as we assume that the HTTP roundtrip will be more than sufficient for the server to have invalidated (and perhaps even refreshed) its response.
