Trying to update DocumentEventMap type

Hello, I am working on adding support for the onvisibilitychange event listener to the document object in PR #359.

I was wondering how to also add compatibility for

document.addEventListener('visibilitychange' someEventHander)

which would mean adding the visibilitychange property to the DocumentEventMap interface.

However adding that property to addedTypes.json does not modify this interface in dom.generated.d.ts. Is there another way to submit a change to that?

The code has been changed, now adding this to addedTypes.json will work:

{
  "Document": {
    "events": {
      "event": [
        {
          "name": "visibilitychange",
          "type": "Event"
        }
      ]
    }
  }
}
