Fixed dropdown filter input not focusing after transition
What does this MR do?
The dropdown currently focuses the input field as soon as it is opened or after the AJAX request, which works great if the request is a little slow. If you try to open it again it will not focus on the field because of the transition.
This merge request fixes that by waiting for the transitionend
event before focusing the filter input field.
