// Bug 742944 - Do window.open from inside <iframe mozbrowser>.  But then
// reject the call.  This shouldn't cause problems (crashes, leaks).
//
// This is the same as OpenWindowRejected, except we "reject" the popup by not
// adding the iframe element to our DOM, instead of by not calling
// preventDefault() on the event.
