Nested arrays don't render correctly

[mikerjacobi]

I have a GraphQL type for a Polygon which is a list of points, implemented as an array of array of floats:

type Polygon {
  type: String
  coordinates: [[Float]]
}

It renders without the nested array

I believe this is related to this code, which only has handling for standard arrays, and not nested arrays.

I also noticed this with the newest spectaql version on npm (v3.0.4) when ontologyTreeIdOrSets: [[ID!]!] argument of a query had turned into ontologyTreeIdOrSets - [ID!] in the generated documentation. This makes all queries that have nested arrays as arguments be typed incorrectly → such queries from the documentation fail validation if used.

If anyone knows of a workaround for this—other than not using nested arrays in the first place, that is—please share! Thank you!
