It's a shame this is blocking the removal of chrome/browser as a dependency for
the dialog implementations... Perhaps there's another way to enforce this or
loop in this helper? +pkotwicz@chromium.org for thoughts.

The right place for this logic is in WindowModalityController. Checking this in
WindowModalityController would require some work (and perhaps a new
ui::ModalType: ui::MODAL_TYPE_APP, which better reflects the modal behavior of
JS dialogs) I can discuss in more details if you guys are interested.

There are other places where this logic could be moved but I cannot think of a
less hacky place.

Done.
