fallback doesn't work

i18n.mjs:1 Uncaught Error: [svelte-i18n] Locale "it-IT" not found.
    at Object.ct.set (i18n.mjs:1)
    at locale.js:17
    at main.js:12

I have english (en) and german (de) defined as my locales, but if I change my language in Chrome to Italian (it-IT). It fails with the above error.

Here is my config:

import { locale, dictionary, getClientLocale } from 'svelte-i18n'
import { de, fr, en } from './i18n'

// Define a locale dictionary
dictionary.set({
  de,
  fr,
  en,
})

// This is a store, so we can subscribe to its changes
locale.subscribe(() => {
  console.log('locale change')
})

// svelte-i18n exports a method to help getting the current client locale
locale.set(
  getClientLocale({
    // the fallback locale, if didn't find any
    fallback: 'en',
    // set to 'true' to check the 'window.navigator.language'
    navigator: true,
    // // set the key name to look for a locale on 'window.location.search'
    // // 'example.com?locale=en-US'
    // search: 'lang'
  }),
)

// Set the current locale to en-US
// locale.set('en')

I just get a blank page (demo: https://puump.com)

I’m downgrading until you figure out how to fix your bugs.

Fixed on v2.0.1. Please, see https://github.com/kaisermann/svelte-i18n/wiki#setting-the-initial-locale to set the initial and fallback locales in a simpler way 😁
