Selector breaks when regions and standalone languages are used

[chrisdmacrae]

If you provide bare languages and regionalized languages, it seems like you can't select the languages:

[
  {
     language: "en",
  },
  {
     language: "fr",
  },
  {
     language: "en",
     region: "PE"
  },
  {
     language: "fr",
     region: "PE"
  }
]
