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

Chrome

Describe the Bug

Using the config below, getRelativeLocaleUrl("es", "/") outputs /es/ instead of /es. It seems that this only happens with the home path. This also affects the other i18n functions.

const config = {
  trailingSlash: 'never',
  build: {
    format: 'file',
  },
  i18n: {
    defaultLocale: "en",
    locales: ["en", "es"],
    routing: {
      prefixDefaultLocale: false,
    }
  }

What's the expected result?

I expected that trailingSlash: 'never' option should never output urls with trailing slash.
