I have not downloaded any of the new updates recommended by EP, but I was very happy to notice today that I can now see the tours build with TW 6.5 in Chrome.
For instance - this tour is now working:

SO I guess Chrome is updated with fixes of this problem. Wuuhuuuu
You might want to look at the position of your loading bar and make the correct adjustments. I can confirm your tour works fine with Google Chrome browser.
