Clicking on a typeahead multiselect should auto-enable the input

[cameronpettit]

Clicking on a typeahead multiselect when there are already items selected does not immediately enable the input field with cursor ready to type. This is because the empty space following multiselect items triggers focus on the multiselect typeahead input but for some reason the text cursor only appears if the input element itself is clicked, which only is clickable when the field is already focused.

This leads to users having to doubleclick the field to get the right input.
