javascript - window.open() returns null in IE11 if opening

In IE on Windows 10 with default settings, if I perform a window.open() against an external internet site from a page on my local machine or a server on my local network, I get null.

See my repro below. This doesn't happen in IE on Windows 7 or Google Chrome.

Interestingly, if I turn on "Enable Protected Mode" for the Intranet Zone (so that Protected Mode are the same in the Intranet Zone and Internet Zone), then the problem goes away. However, I need this to work without requiring users to do this.

I haven't found any clear Microsoft documentation that explains this behavior. I raised an issue on this on the EdgeHTML issues site, but wanted to see if the munity on SO has any insight into why this is happening.

Thanks!

It seems that protected mode doesn't allow to open new window outside of the current domain, so you can try to open the window with a blank page and after update the location.

<script>
    var popupWindow = null;

    function openWindow() {
        popupWindow = window.open('', '_blank', 'left=100;top=100;height=100;width=100');
        popupWindow.location = 'http://microsoft.';
    }

    function checkWindowStatus() {
        if (popupWindow) {
            document.getElementById('status').innerHTML += '- Truthy reference. Closed? ' + popupWindow.closed + '</br>';
        } else {
            document.getElementById('status').innerHTML += '- Falsy reference: ' + popupWindow + '</br>';
        }
    }
</script>
