This happens in connector, maintenance, proxy, service and SLA forms.

List of affected forms increases with each new version. First appeared with service and SLA clone/edit forms in Zabbix 6.0.

Steps to reproduce:

1. Open edit form;
2. Press "Clone".

Result:
No autofocus field is focused.

Expected:
Autofocus field is focused the same way as in forms where whole view is reloaded (e.g., host edit form).
