button after link issue. - depend on vue version

[volski]

so the issue is:
https://jsfiddle.net/Lcgbq05s/5/

if i use <script src="https://cdn.jsdelivr.net/vue/2.0.3/vue.js"></script> - link appears and button works fine
if i use <script src="https://cdn.jsdelivr.net/vue/latest/vue.js"></script> - link disables and button works fine

the reason for using latest - is that in the 2.0.3 the select list does not appear.
