Concerning roof geometry from floor js json import

Issue overview

I am using the following code to import this floor js json into OpenStudio

 floorplan = OpenStudio::FloorplanJS::load(floor_js_json_data)
  if floorplan.empty?
    raise "Cannot load floorplan from '#{floorplan_path}'."
  end

  scene = floorplan.get.toThreeScene(true)

  rt = OpenStudio::Model::ThreeJSReverseTranslator.new

  model = rt.modelFromThreeJS(scene)

The space seen in the screenshot below:

Produces the roof geometry below:

Although the floor geometry comes out just fine
