Actually, #704 is not fixed by this change.
Paste handler immediately calls ctrl.select in loop and in case tagging-label="false" ctrl.select tries to parse text from ctrl.search which is not filled in because e.preventDefault() was called in paste handler.

To fix this we could add timeout before calling ctrl.select from paste handler, and remove e.preventDefault() from it something like this:

ctrl.searchInput.on('paste', function (e) {
    var data = e.originalEvent.clipboardData.getData('text/plain');
    if (data && data.length > 0 && ctrl.taggingTokens.isActivated && ctrl.tagging.fct) {
        var items = data.split(ctrl.taggingTokens.tokens[0]); // split by first token only
        if (items && items.length > 0) {
            $timeout(function () {
                angular.forEach(items, function (item) {
                    var newItem = ctrl.tagging.fct(item);
                    if (newItem) {
                        ctrl.select(newItem, true);
                    }
                });
            });
            e.stopPropagation();
        }
    }
});
