DB2 ui-template adding CSS transitions for table rows

Hi I'm trying to add a css transition on a expanded row using the vuetify 3 v-data-table component inside a ui-template in Dashboard 2.0. I click anywhere on the row to expand the row for more information. All of that works great, but I can't get a smooth transition to happen. I've tried several props, v-expand-transition. I used the v-bind:class to dynamically add a class name and used CSS to do the transition or animation. The expanded component opens and closes with no problem, but no transition.

NR version: 3.1.5
Dashboard 2.0 version: 1.4.1

Here's my code

<template>
  <v-data-table :headers="visibleHeaders" :items="items" :items-per-page="itemsPerPage" class="elevation-1"
    v-model:expanded="expanded" item-key="id">
    <template v-slot:top>
      <v-toolbar flat>
        <v-toolbar-title>Device Table</v-toolbar-title>
        <v-spacer></v-spacer>
        <v-dialog v-model="dialog" max-width="500px">
          <template v-slot:activator="{ props }">
            <v-chip color="primary" pill class="ma-4" variant="outlined" v-bind="props" @click="dialog = true">Add New Exhibit</v-chip>
          </template>
          <v-card>
            <v-card-title>
              <span class="text-h5">{{ formTitle }}</span>
            </v-card-title>

            <v-card-text>
              <v-form ref="form" v-model="valid">
                <v-text-field v-model="editedItem.host" label="Host" :rules="[v => !!v || 'Host is required']">
                </v-text-field>
                <v-text-field v-model="editedItem.ip" label="IP"></v-text-field>
                <v-text-field v-model="editedItem.mac" label="MAC"></v-text-field>
                <!-- Add more form fields for other properties -->
              </v-form>
