Incorrect error for bad argument of a DOM type

```ts
declare var ohno: new () => Node;
declare function ff(t: Node): void;
ff(ohno)
```

**Expected behavior:**
Error: "Argument of type 'new () => Node' is not assignable to parameter of type 'Node'

**Actual behavior:**
Type 'new () => Node' is not assignable to type 'Node'.

Only seems to repro when both the source and target types are in the DOM.
