Detect blocked pop-up in Chrome

Question

Ok so I am using Chromium for Ubuntu 9.10 and cannot get this working using the normal means of detecting a pop-up blocker which are...

var popup = window.open(...);
var blocked;
if(!popup) {
    blocked = true;
} else {
    blocked = false;
}

Also, the accepted solution in this SO post, http://stackoverflow.com/questions/668286/detect-blocked-popup-in-chrome, does not work.

Answer 1

If it's a page on the same domain, check popup.innerHeight. If it's 0, the popup was most likely blocked.

Answer 2

I have tried getting the innerHeight too. When the browser is set to disallow popups, the result is zero as expected. However, when I allow popups, the result remains at zero when I can see the popup!

Has anyone found a solution to this?
