Description

https://jsfiddle.net/0f2enztx/

Steps to reproduce

Using Nuxt 2.0.0, Vue 2.5.17, Vue-Multiselect 2.1.0

In nuxt.config: plugins:[ ... '~/plugins/vue-multiselect', ... ] css: [ '~/assets/scss/main.scss', 'vue-multiselect/dist/vue-multiselect.min.css', ],

Look at jsfiddle to for the remaining part of the configuration.

Expected behaviour

Like the demo I expect that everything works fine, and jsfiddle prove exactly this.

Actual behaviour

I detect that when i navigate with this.$router.push method to the page that contains vue-multiselect html tag and I try to select an option, vue-dev-tool say to me that two events are dispatched: an input event with a payload (array) and a select event with payload (object - that is the category selected by the user),but the selected category is not highlighted by vue multiselect and is not selected.

Strange thing? When I reload manually the page this behavior disappear and everythings work weel.

Important notes

v-model is set on a computedProperty with only the get method implemented.

Research direction
This issue likely involves a lifecycle or reactivity problem when navigating via vue router. The component works on page reload but not on programmatic navigation, suggesting that the component is not properly re initialized or the v model computed property (getter only) does not trigger reactivity. Investigate the vue multiselect component lifecycle and how it handles updates. Check if there are known issues with vue router and component re rendering. Look at the component's source code for any 'activated' or 'deactivated' hooks. Possibly the component needs a key or a watcher on the model value.
