Data:

{
    "$schema": "test_schema.json",
    "name": "Hi"
}

Schema:

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "$id": "https://example.com/example",
    "title": "test",
    "properties": {
        "name": {
            "type": "string"
        }
    },
    "additionalProperties": false
}

VS Codes built in JSON feature markes a “problem” (yellow underline below "$schema") in my data. VS Code validates the data with the schema referenced in the data. So the reference to the schema itself breaks the rules of the schema it is referencing to. Property $schema is not allowed.
Removing "additionalProperties": false from the schema solves it. But I want to keep it. Is this a VS Code bug or did I do something wrong?
