 // 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.
