Seperators are strict for extractLanguageDisplayNames

Hi, I'm trying to retrieve the display name for the locale en-us but the function returns {}. If I normalize the locale to en_us then it will return properly. According to the readme, any function that takes a localeId should be able to accept - or _ correct?

I also found a weird bug (?) for en-gb where it only returns

{ 
  arn: 'Araucanian',
  bax: 'Bamum',
  en_gb: 'UK English',
  en_us: 'US English',
  tzm: 'Central Morocco Tamazight',
  wal: 'Walamo' 
}

yet normalizing the locale returns

{ arn: 'Araucanian',
  bax: 'Bamum',
  en_gb: 'UK English',
  en_us: 'US English',
  tzm: 'Central Morocco Tamazight',
  wal: 'Walamo',
  aa: 'Afar',
  ab: 'Abkhazian',
  ace: 'Achinese',
  ach: 'Acoli',
  ada: 'Adangme',
  ady: 'Adyghe',
  //...
  }

Confirmed. The display names are actually defined in the en locale, but it looks like they don't get inherited properly.

Fixed in 2.3.4. Thanks for reporting!
