Bugzilla

From Blink's `document.idl`:
```
    // Named getter is implemented without IDL code generation for better
    // performance. See local_window_proxy.cc.
    // getter object (DOMString name);
```
and the implementation is such that it only exposes named props for instances of the internal `HTMLDocument` class, and only ones that are in a `Window` context.  What it's doing is _definitely_ not matching the HTML/IDL specs.

I haven't dug into the WebKit code here yet.

What it's doing is _definitely_ not matching the HTML/IDL specs and can't even be expressed in those terms, as far as I can see.
