 * The intended value for `LocaleRegion` is in the format of `language[-country]` where `language` is the 
 2-letter code from [ISO 639](https://www.iso.org/iso-639-language-codes.html) and `country` is the 
 2-letter code from [ISO 3166](https://www.iso.org/standard/72482.html).
-* By default, the `LocaleRegion` will be set as the value for the Limited option in the browser.
-That means that if the OS region and the display language share the same language code, 
-like 'en-GB' and 'en-US', the value will be set to the OS region.
