Expected behavior

I would expect that the time picker rerenders, after changing the value of the v-model. But it is not reactive and shows still the initial value (08:00)

Resources (screenshots, code snippets etc.)

<template>
  <MDBTimepicker label="Select a time" v-model="picker" :hoursFormat="24" />
  <MDBInput label="input" v-model="picker"/>
</template>

<script>
  import { MDBTimepicker, MDBInput } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';
  export default {
    components: {
      MDBTimepicker,
      MDBInput,
    },

    setup() {
      const picker = ref('08:00');

      setTimeout(() => {
        picker.value = '12:00';
      }, 2000);

      return {
        picker,
      };
    },
  };
</script>
