Vue.js keyup events and v-model length on Android not working as expected

On Android the length of v-model is returning 0 on keyup unless its a number or the space bar key. Does anyone know why that is and how to make it fire the keyup event no matter what key it is and get the length? Here is a cleaned up version of what I have:

<template>
  <div class="typeahead">
    <input
      v-model="query"
      v-on:keyup="suggestTerms"
      >
  </div>
</template>

<script>
export default {
  data () {
    return {
      query: '',
    }
  },
  methods: {
    suggestTerms () {
      console.log('query length = ' + this.query.length);
    }
  }
}
</script>

P.S. This works on every browser and device except Android.
