class AutocompleteTagsWidget in Entity reference 8
Plugin implementation of the 'entityreference autocomplete-tags' widget.
@todo: Check if the following statement is still correct The autocomplete path doesn't have a default here, because it's not the the two widgets, and the Field API doesn't update default settings when the widget changes.
