support Vuetify

Is your feature request related to a problem? Please describe.

I tried to use vuetify and after creating a simple text-field it didn't show up in the popup and I noticed an error in the console of the popup says "Cannot read property 'rtl' of undefined". after some troubleshooting it seems like the $vuetify global variable is not passed to the plugin.

// popup main.js

// import Vuetify from 'vuetify'
// import 'vuetify/dist/vuetify.min.css'
// Vue.use(Vuetify)

// import ElementUI from 'element-ui'
// import 'element-ui/lib/theme-chalk/index.css'
// Vue.use(ElementUI)
