Dropdown: UpArrow triggers "Uncaught TypeError: this.visibleOptions.slice(...).findLastIndex is not a function" Firefox, Nuxt 3

[ian4uia]

Describe the bug

In Firefox from a Nuxt 3 app. When navigating the Dropdown options via keyboard, if any option other than the top is highlighted then pressing the up arrow key will trigger an error shown in the console as:
Uncaught TypeError: this.visibleOptions.slice(...).findLastIndex is not a function

To Reproduce from a shell with node v18.1.0 installed.

npx nuxi init nuxt3-prime-dropdown-bug
cd nuxt3-prime-dropdown-bug
yarn add primevue
mkdir plugins
touch plugins/primevue.ts

Add below code to the primevue.ts file that you just created:

// plugins/primevue.ts
import { defineNuxtPlugin } from '#app'
import PrimeVue from 'primevue/config'
import Dropdown from 'primevue/dropdown'
export default defineNuxtPlugin((nuxtApp) => {
  nuxtApp.vueApp.use(PrimeVue, { ripple: true })
  nuxtApp.vueApp.component('Dropdown', Dropdown)
})

Now update nuxt.config.ts

import { defineNuxtConfig } from 'nuxt'

// https://v3.nuxtjs.org/api/configuration/nuxt.config
export default defineNuxtConfig({
  build: {
    transpile: ['primevue']
  },
  css: [
    'primevue/resources/themes/md-light-indigo/theme.css',
    'primevue/resources/primevue.min.css'
  ],
})

And create the test page:

mkdir pages
touch pages/index.vue

And add the code below:

<template>
  <div>
    <h3> {{ country }}</h3>
    <Dropdown
      v-model="country" :options="countries" optionLabel="name" optionValue="code"
    />
  </div>
</template>

<script setup lang="ts">
const countries = ref([
  {name: 'Australia', code: 'AU'},
  {name: 'Brazil', code: 'BR'},
  {name: 'China', code: 'CN'},
  {name: 'Egypt', code: 'EG'},
  {name: 'France', code: 'FR'},
  {name: 'Germany', code: 'DE'},
  {name: 'India', code: 'IN'},
  {name: 'Japan', code: 'JP'},
  {name: 'Spain', code: 'ES'},
  {name: 'United States', code: 'US'}
]);
const country = ref('AU')

</script>

Now update app.vue and change <NuxtWelcome /> to <NuxtPage />
And finally:
yarn run dev
