    at <anonymous>:2:2895
    at n.timeout (<anonymous>:2:5652)

Example:

Steps to reproduce:

1. Open the list of hosts or any other entities that have configuration in a dialog.
2. Open browser console and narrow the browser window so that the horizontal scrollbar would appear
3. Click one any existing entity to open its configuration (for example of "Zabbix server" host name)
4. In the opened configuration form click "Cancel" to close the form
5. Once the form is closed, drag the horizontal scrollbar to the right
6. Wait for a couple of seconds

Result: the above mentioned browser console error appears.
Expected: no browser console errors should appear.
