Steps to reproduce:

1. Set 'User settings' --> 'Profile' --> 'Refresh' to 5 or 10 seconds
2. Go to 'Monitoring' --> 'Hosts' – Click on hostname --> Select Dashboards
3. Navigate to 'System performance' tab and scroll down a bit
4. Wait for a few seconds and an unrequested page reload should occur

Result:
unrequested page reload
Expected:
Dashboard page should not reload
