Attendees: focus search field after adding autocomplete item
Is your feature request related to a problem? Please describe.
The attendees tab in the event sidebar has a field to "Search for e-mails, users, contacts, resources or rooms". When typing a search term, it shows an autocomplete list with items that can be selected using arrow keys and confirmed using return.
After confirming/adding an item (e.g. a user), the search field loses it focus. This requires me to manually refocus the search field again with the mouse. This is tedious, especially for events with several attendees.
Describe the solution you'd like After an attendee is selected from the autocomplete list, the search field should be focussed again.
