Problem description

Closing these selectors/popovers should return the focus to the trigger that opened them. It seems that focus is completely lost currently and goes to the first element on the page. This seems to be an issue on quite a few popovers so I have grouped these together.

Expected behavior

Focus should be returned to the trigger element that opened the selector/popover.
