Javascript window.location returning two different values?

Question

I am using a JS popup window for an Oauth2 Implicit Grant. I'm using JS to monitor for URL changes to get the code grant.

    newWindow.addEventListener('unload', function(e)
    {
        console.log(e.currentTarget.location);

        if (e.currentTarget.location.href.includes('code='))
        {
            var url = new URL(e.currentTarget.location.href);
            alert(url.searchParams.get('code'));
        }
    });

The problem I am having is that the location field is giving two different values for the href parameter.

As you can see in the image, the href parameter has two different values. How do I make sure I always get the second value?

about:blank... but console.log lists the other address in the drop down. — Jason Axelrod

@JasonAxelrod Is the question is related to console values, working as expected? — Prashant Pimpale

The Location is evaluated some time before.

If you hover over the little blue i icon, it says:

Value below was evaluated just now.

@PrashantPimpale, to me, the solution is to avoid console when possible.
