Anchor on property which uses alias fails validation

Schema:

{
  "title": "Field definitions schema!",
  "$schema": "http://json-schema.org/draft-04/schema#",
  "definitions": {
    "field": {
      "type": "object",
      "additionalProperties": false,
      "required": ["label"],
      "properties": {
        "label": { "type": "string" }
      }
    },
    "model": {
      "type": "object",
      "additionalProperties": false,
      "properties": {
        "props": {
          "type": "object",
          "additionalProperties": { "$ref": "#/definitions/field" }
        }
      }
    }
  },
  "type": "object",
  "additionalProperties": { "$ref": "#/definitions/model" }
}

Document:

Named:
  props: &NamedProps
    name:
      label: Name

Timestamped:
  props: &TimestampedProps
    <<: *NamedProps
    ts:
      label: Timestamp

Record:
  props:
    <<: *TimestampedProps # commenting out this line removes the errors
    id:
      label: ID

Looks like it’s incorrectly adding a layer of nesting or something?

I haven’t been able to look into it but my hunch is that the first merge key is being properly expanded but the second one isn’t, leading to the error. The code that does that is here: https://github.com/redhat-developer/yaml-language-server/blob/master/src/languageservice/parser/jsonParser07.ts#L951 if you want to poke around

Anything I can do to help? My yamls are all red 😦
