Selectize vue component closing dropdown after selection

Trying to create a simple selectize vue component but I'm having issue where whenever I select an option and using v-model within the component, the dropdown automatically closes while removing the v-model the dropdown stays open until the specified max items are reached.

HTML

<div id="app">
  <p>With Model: {{ selected }}</p>
  <selectize v-model="selected" :options="options" data-max-items="2"></selectize>

  <p>Without Model: {{ selected }}</p>
  <selectize :options="options" data-max-items="2"></selectize>
</div>

JS

Vue.component('selectize', {
  props: ['options', 'value'],

  template: '<select><slot></slot></select>',

  mounted() {
    $(this.$el).selectize({
      onInitialize: () => {
        this.$el.selectize.setValue(this.value, true)
      },

      onChange: (value) => {
        this.$emit('input', value)
      },

      ...this.mergedSettings,
    })
  },

  computed: {
    mergedSettings() {
      return $.extend({
        options: this.options,
      }, $(this.$el).data())
    },
  },

  watch: {
    value(value) {
      this.$el.selectize.setValue(value, true)
    },
  },
})

new Vue({
  el: "#app",
  data: {
    options: [
      { value: 1, text: "One"   },
      { value: 2, text: "Two"   },
      { value: 3, text: "Three" },
      { value: 4, text: "Four"  },
    ],

    selected: [],
  },
})

I also created a jsfiddle: https://jsfiddle.net/uk0g69s4/19/

I'm not proud of this solution but it is the better thing I could figure out.

Create a SELF_CHANGED attribute to check if the change was triggered internally or externally...

Vue.component('selectize', {
  props: ['options', 'value'],
  data() {
    return {
      SELF_CHANGED: false
    }
  },
  template: `
    <select>
        <slot></slot>
    </select>
  `,
  mounted() {
    $(this.$el).selectize({
      onInitialize: () => {
        this.$el.selectize.setValue(this.value, true)
      },

      onChange: (value) => {
        this.SELF_CHANGED = true
        this.$emit('input', value)
      },

      ...this.mergedSettings,
    })
  },

  computed: {
    mergedSettings() {
      return $.extend({
        options: this.options,
      }, $(this.$el).data())
    },
  },

  watch: {
    value(value) {
      if (!this.SELF_CHANGED) {
        this.$el.selectize.setValue(value, true)
      }
      this.SELF_CHANGED = false
    },
  },
})

new Vue({
  el: "#app",
  data: {
    options: [{
        value: 1,
        text: "One"
      },
      {
        value: 2,
        text: "Two"
      },
      {
        value: 3,
        text: "Three"
      },
      {
        value: 4,
        text: "Four"
      },
    ],
    selected: [],
  },
})
body {
  background: #20262E;
  padding: 20px;
  font-family: Helvetica;
}

#app {
  background: #fff;
  border-radius: 4px;
  padding: 20px;
  transition: all 0.2s;
}
