Arrays confuse the auto-completer

[jneem]

The auto-completer is not good at auto-completing records inside arrays. For example, in

let LanguageConfiguration = {
  name | String,
}
in
let HxLang = { language | Array LanguageConfiguration, .. } in
{
  language = [
    { na }
  ]
}
  | HxLang

we don't get an autocompletion for "name". If we drop the arrays, we get the autocompletion.
