YAML autocompletion and validation works only for the first YAML definition in a file (schema through modeline)

Describe the bug

YAML autocompletion and validation works as expected for the first YAML definition in the file.

Validation works also as expected.

When I try to add another YAML definition into the same file, there is no autocompletion or validation available.

Expected Behavior

It would be great if you can add multiple resources with the same or different schema in the same file.

Steps to Reproduce

My schema "test.schema.json" is

{
  "properties": {
    "my_key": {
      "description": "My string",
      "enum": ["my_value"],
      "type": "string"
    }
  },
  "type": "object"
}

Environment

• Windows
• Mac
• Linux
• other (please specify)

Start by reproducing the issue in VS Code with the provided test.schema.json and multiple YAML definitions using schema-through-modeline. Trace the YAML completion and validation behavior for the first and subsequent definitions; done means each resource receives the expected schema-based completion and validation.
