vscode-yaml: Array item properties are created with the wrong indent

I have a JSON schema which contains an array property. The array item type is an object with properties. The desired layout is like this:

install:
  - helm:
      name: foo
  - helm:
      name: bar

When I add the array using tab-completion, RH YAML correctly inserts a starting array element with the correct indentation:

in<HIT TAB TO AUTOCOMPLETE>

=>

install:
  - helm:
      name: <CURSOR POSITIONED HERE>  # This is correct

But when I add a second array element by tab-completing the name, it does not indent the sub-properties:

install:
  - helm:
      name: foo
  - he<HIT TAB TO AUTOCOMPLETE>

=>

install:
  - helm:
      name: foo
  - helm:
    name: <CURSOR HERE>   # Note name is *NOT* indented from its parent

Furthermore, our real scenario is that the array can contain multiple different kinds of item (which is why we have the helm parent name rather than just an array of tuples). So our JSON schema specifies "items": { "anyOf": [ { "$ref": "...helm..." }, { "$ref": "...exec..." }, ... ] }. In this case, even with only a single option in the “anyOf”, no element is auto inserted (correctly, as RH YAML could not know which of the anyOf options to take), and the user must explicitly insert the first array element, which is then indented incorrectly

# With the anyOf variant of the JSON Schema

in<HIT TAB FOR AUTOCOMPLETION>

=> 

install:
  - <CURSOR HERE>  # This is okay

=>

install:
  - he<HIT TAB FOR AUTOCOMPLETION>

=>

install:
  - helm:
    name: <CURSOR HERE>  # Incorrect indentation

Here is the simplified JSON Schema which I used to reproduce the issue:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "definitions": {
    "installStep": {
      "properties": {
        "helm": {
          "additionalProperties": false,
          "properties": {
            "name": {
              "type": "string"
            }
          },
          "required": [
            "name"
          ],
          "type": "object"
        }
      },
      "required": [
        "helm"
      ],
      "type": "object"
    }
  },
  "properties": {
    "install": {
      "items": {
        "anyOf": [
          {
            "$ref": "#/definitions/installStep"
          }
        ]
      },
      "type": "array"
    }
  },
  "type": "object"
}

Note that this is the ‘anyOf’ schema to show the second part of the issue (which is our real environment). To reproduce the first part of the issue, remove the anyOf from around the $ref in the items schema (or I can send you that schema too).

Please let me know if you need any more information.
