TypeError: object null is not iterable

The following test case errors out if present. It does not error out when either of the two issues are fixed:

1. colon is removed from id attribute
2. div is removed from p

Reduced test-case

<div id="test-id: ">
    <p>
    <div>
    </div>
    </p>
</div>

Configuration

{
  "extends": ["html-validate:recommended"]
}

Expected result

Expected the document to be invalid (because there are errors).

Actual result

Validator failed with:

    TypeError: object null is not iterable (cannot read property Symbol(Symbol.iterator))
