> Steps to reproduce:
> 1. Start "Add Host" wizard. On "Review" step hit "Deploy" button. Progress
> bar appears. While it is not totally completed, click on the previous step
> (look at screen1). Progress bar still overlaps selected wizard page.
> 2. After progress bar finishes, the wizard automatically switches to
> "Review". Progress bar still overlaps it. (look at screen2)
> 3. Hit "Deploy" button again. Error message appeares that host was already
> added to cluster (look at screen3)
> 4. If you close "Add Host" wizard with "X" button and close error message,
> you get frozen WebUI with empty progress bar (look at screen4). However, it
> is all right after refresh.
