Why flashing title page?

When you call the method
history.pushState(null, title, url);
Title page (browser tab) is flashing, that is, after actuation method title changes to the url of the site, and then back to what it was, it happened fast, in about 1 second, but a bit annoying, why is this happening? How to fix? Despite the fact that the title of the document, I personally don't touch.
This effect is observed in chrome.

If you disable the plugin history.js then all the rules, he emulates the operation history api for older browsers. Why it affects the latest chrome?
