Changing browser language setting does not change the word from i18n

[mengxi-ream]

I use https://wxt.dev/i18n.html

and then start dev mode by pnpm dev, I tried to change the language of chrome

But this won't affect my UI, my UI is still in English.

What I did in code is just the code from https://wxt.dev/i18n.html

export default defineConfig({
  modules: ['@wxt-dev/i18n/module'],
  manifest: {
    default_locale: 'en',
  },
});

import { i18n } from '#i18n';

i18n.t('helloWorld'); // "Hello world!"

I have en.yaml and zh.yml, zh-CN.yml files

I realize I can only change the language of my Mac System to change the language inside the web browser.

For future reference, here's how to change Chrome's language: https://developer.chrome.com/docs/extensions/reference/api/i18n#how-to-set-browsers-locale

It varies for each OS
