Unable to extend a type

#1

I am trying to extend an existing spec, including a type extension. It works fine if base type has no type: specified. Otherwise, it shows the following error

Effectively, this bug makes extensions unusable. Has anyone seen this problem before ?

Thanks

Original RAML Spec:

#%RAML 1.0 
title: An example
version: v1
mediaType: application/json
baseUri: http://api.example.io/

types: 
  existing_type:
    properties:
        existing_property:
            type: string

The following extension work correctly:

Example 1. Works - existing type is extended correctly and has 2 properties as a result.

#%RAML 1.0 Extension 
usage: Type Extension Example
extends: ./api.raml

types: 
  existing_type:
    properties:
      new_property:
        type: string

Example 2: Does NOT work. In the original RAML, “type: object” is added (it can reference any other type). The extension from example 1 no longer works.

#%RAML 1.0 
title: An example
version: v1
mediaType: application/json
baseUri: http://api.example.io/

types: 
  existing_type:
    type: object
    properties:
      existing_property:
        type: string
