Fix issues with hiding the autocomplete when trying to focus the search field.
Automatically update the search field value with the searched value.
Blank state showing `No quicktexts found` when the autocomplete is active and we search using the search field, but no quicktexts are found.

Still some issues with the search and the caret:
* Results returned from from the .getFiltered requests are sometimes wrong.
* Probably because of range issues, lots of times we're matching the wrong text.
