form reset not working with custom components as direct child to v-form

[avxkim]

Form component:

<v-form ref="form">
  // doesn't reset
  <child-component v-model="select" :items="[1, 2, 3, 4, 5]" />
  // does reset
  <v-select v-model="select" :items="[1, 2, 3, 4, 5]" />
  <v-btn @click="reset">Reset</v-btn>
</v-form>

// data
data() {
  return {
    select: null,
  }
}
 
// reset method
reset() {
  this.$refs.form.reset()
},

Child component:

<div>
  <v-select :value="value" :items="items" @change="$emit('input', $event)">...</v-select>
</div>

// props
props: {
  value: {
    type: [Number, String],
    default: null,
  },
  value: {
    type: Array,
    required: true,
  },
}

It doesn't clear child-component's select value, but if i use v-select as a direct child to v-form instead, it does work as expected.
