Unable to auto-complete the second block

VSCode version: Version 1.36.1 (1.36.1)
Plugin version: 0.4.1

My schema is

{
    "$id": "https://example.com/address.schema.json",
    "$schema": "http://json-schema.org/draft-07/schema#",
    "title": "poc",
    "description": "poc",
    "type": "object",
    "properties": {
      "name": {
        "description": "name",
        "type": "string"
      },
      "rules": {
        "description": "rules",
        "type": "array",
        "items": {
          "type": "object",
          "properties": {
            "method": {
              "description": "method",
              "type": "string",
              "enum": ["GET", "POST"]
            },
            "path": {
              "type": "string",
              "description": "path"
            }
          },
          "required": ["method", "path"]
        }
      }
    },
    "required": ["name", "rules"]
  }

Settings is

{
    "yaml.schemas": {
        "./yaml.schema.json": "*.yaml"
    }
}

It seems the auto-complete will not work on the second block

For example,

you type rules, vscode auto completes, and then you type name, nothing will show

you type name, vscode auto completes, and then you type rules, nothing will show

Reproduce the issue in VS Code 1.36.1 with plugin 0.4.1 using the schema and yaml.schemas settings shown in the report. Compare completion after creating the first and second objects in the rules array, and verify that both root properties and nested properties are offered when the behavior is fixed.
