If this issue only occurs in one browser, which browser is a problem?

No response

Describe the Bug

This is my astro.config.ts:

export default defineConfig({
  trailingSlash: 'never',
  i18n: {
    locales: ['en', 'fr'],
    defaultLocale: 'en',
  },
});

using getRelativeLocaleUrl('fr', '') or getRelativeLocaleUrl('fr', '/') returns /fr/ (a string with a trailing slash) even though trailingSlash: never is set in the config. The same goes for getAbsoluteLocaleUrl

What's the expected result?

If I defined trailingSlash: never, I expect that getRelativeLocaleUrl and getAbsoluteLocaleUrl return paths without a trailing slash (with the possible exception of the root path)
