@hdodda I watched the screencast and did that same exact thing you did but saw the problem I have been seeing.

So I tried using a new profile (by adding a new person under the people tab) and even updated my OS to 10.12.3 however I am still seeing the issue. A weird thing I noticed is when I have the same code in jsfiddle, I don't experience the problem which really makes no sense to me.

I even went a far as completely removing the chrome install and reinstalling (uninstalling with AppCleaner / removing the ~/Library/Application Support/Google/Chrome folder) and I still was noticing the same issue. I also tried all the different mac show scroll bar settings with no luck. I also had a colleague try on his computer (same Chrome / OS version) and still had the same issue.

If there is anything else I can do to help you figure out what is going on here, let me know.

@hdodda I did test this on browerstack and while it did work properly there, it is using a slightly older version (56.0.2924.76).

@hdodda In the spirit of due diligence, I had another colleague try the codepen (same Chrome version / different Mac OS X version) and it resulted in the same issue.

@hdodda I have attached a basic HTML file that when I load into chrome shows the issue to try to remove anything that online code editors might be doing (as the scrolls works different for this code in different editor like codepen, jsfiddle, jsbin, etc.)
