before-adding-tag hook not works when v-model is empty

[Tantacula]

Demo here: https://codepen.io/anon/pen/gJEorL

When I try to add the tag by clicking on autocomplete element 'before-adding-tag' event bubbles only if v-model is not empty.

Try to click on the input field in a demo and select item from autocomplete. Then enter any symbol and select any item again. Hook works only in the second case.

i have same problem, if you edit a tag and clear with the backspace the content, it not delete continue open it until you push some value. enter or tab keys not work.
