javascript - Popstate on page's load in Chrome

Question

I am using History API for my web app and have one issue. I do Ajax calls to update some results on the page and use history.pushState() in order to update the browser's location bar without page reload. Then, of course, I use window.popstate in order to restore previous state when back-button is clicked.

The problem is well-known — Chrome and Firefox treat that popstate event differently. While Firefox doesn't fire it up on the first load, Chrome does. I would like to have Firefox-style and not fire the event up on load since it just updates the results with exactly the same ones on load. Is there a workaround except using History.js? The reason I don't feel like using it is — it needs way too many JS libraries by itself and, since I need it to be implemented in a CMS with already too much JS, I would like to minimize JS I am putting in it.

So, would like to know whether there is a way to make Chrome not fire up popstate on load or, maybe, somebody tried to use History.js as all libraries mashed up together into one file.

In Google Chrome in version 19 the solution from @spliter stopped working. As @johnnymire pointed out, history.state in Chrome 19 exists, but it's null.

My workaround is to add window.history.state !== null into checking if state exists in window.history:

var popped = ('state' in window.history && window.history.state !== null), initialURL = location.href;

I tested it in all major browsers and in Chrome versions 19 and 18. It looks like it works.
