      Steps to reproduce

      1.  Start CE demo webapp
      2.  Log in into admincentral
      3. Interact with UI (e.g. click a find bar result)

      Expected results

      UI responds.

      Actual results

      Progress bar is pending infinitely (most of the times, although this should be tested repetitively).

      Workaround

      Refresh the browser tab.

      Development notes

      This is caused by UI#push calls before the push connection is established (in our case findbar results).
      Although vaadin has code to handle these pending pushed, this causes the freezing.
