Modal autofocus is broken for dropdown #1900
Description
Thanks to Fomantic-UI 2.9.0 which prevents dropdown open on focus we should focus dropdown field if it is the 1st one in the modal.
Currently we do input field autofocus in
ui/js/src/services/modal.service.js
Line 140 in c535b9b
related to fomantic/Fomantic-UI#2490
once the Fomantic-UI is fixed, we should not need any custom code (the atk.modalService.doAutoFocus function should be dropped)
