Fixes a bug in the way Window sinks events on the outer Window. In some cases, adding a script element to the page will not result in the script element being parsed synchronously, so we need to use the eval command to ensure the events are sunk on the outer Window. IE does not work with the eval command, so we use a deferred binding.
